DESCRIPTION:Establishing asymptotic formulas for moments of L-functions
has been a main goal of analytic number theory for over a century. This
topic is strongly connected to the generalized Lindelöf Hypothesis and v
arious non-vanishing conjectures\, and it has witnessed substantial prog
ress in the last three decades. This one-week workshop will bring togeth
er established and early-career researchers with expertise and interest
in moments and zeros of L-functions to discuss various aspects of the cu
rrent research\, with special emphasis on multiple Dirichlet series\, sh
ifted convolution sums\, random matrix theory\, and spectral theory of a
utomorphic forms. The purpose of this event is to highlight the recent a
dvances in this area and initiate discussions and collaborations among r
esearchers across the different sub-disciplines of this field. In partic
ular\, we are interested in exploring connections between the multiple D
irichlet series approach and the approximate functional equation approac
h to studying moments of L-functions\, perhaps opening up new ways to un
derstanding some of these moments.\n\n\nStarts On: July 25\n\n\nEnds:

DESCRIPTION:Space-time finite element methods (FEMs) are likely to grow
in popularity due to the ongoing growth in the size\, speed\, and parall
elism of modern computing platforms. The allure of space-time FEMs is bo
th intuitive and practical. From the intuitive standpoint\, there is con
siderable elegance and simplicity in accommodating both space and time u
sing the same numerical discretization strategy. From the practical stan
dpoint\, there are considerable advantages in efficiency and accuracy th
at can be gained from space-time mesh adaptation: i.e. adapting the mesh
in both space and time to resolve important solution features. However\
, despite these considerable advantages\, there are numerous challenges
that must be overcome before space-time FEMs can realize their full pote
ntial. These challenges are primarily associated with four-dimensional g
eometric obstacles (hypersurface and hypervolume mesh generation)\, four
-dimensional approximation theory (basis functions and quadrature rules)
\, four-dimensional boundary condition enforcement (well-posed\, moving
boundary conditions)\, and iterative-solution techniques for large-scale
linear systems. In this presentation\, we will provide a brief overview
of space-time FEMs\, and discuss some of the latest research developmen
ts and ongoing issues.\n\n\nSpeaker: David Williams\n\n\nBiography: Da
vid M. Williams is an assistant professor at The Pennsylvania State Univ
ersity in the Mechanical Engineering Department. He came to Penn State f
rom the Flight Sciences division of Boeing Commercial Airplanes and Boei
ng Research and Technology\, where he worked for several years as a comp
utational fluid dynamics engineer. Williams received his M.S. and Ph. D.
in Aeronautics and Astronautics at Stanford University. He holds a B.S.
E. in Aerospace Engineering from the University of Michigan. He has made
significant advances in the design of numerical algorithms for computat
ional fluid dynamic simulations. Currently\, his research focuses on emp
loying high-order Finite Element schemes to more accurately predict unst
eady flows.\n\n\nAffiliation: Penn State University\n\n\nTitle: Space-

DESCRIPTION:Data-driven modeling refers to the use of measurement data t
o infer the parameters and structure of a mathematical model\, or to aid
in forward simulations of a partially known mathematical model. Motivat
ed by problems in collective cell biology\, this talk will explore algor
ithms which automate the map from experimental data to governing differe
ntial equations\, specifically using weak formulations of the dynamics.
We will show that the weak form is an ideal framework for identifying mo
dels from data if the performance criteria are robustness to data corrup
tions\, highly accurate model recovery when corruption levels are low\,
and computational efficiency. We will first demonstrate the advantages o
f the resulting weak-form sparse identification for nonlinear dynamics a
lgorithm (WSINDy) in the discovery of correct underlying model equations
across several key modeling paradigms\, including ordinary differential
equations (ODEs)\, partial differential equations (PDEs)\, and interact
ing particle systems (IPS). We will then discuss more recent extensions
of this framework\, including weak-form identification of PDEs from stre
aming data\, enabling identification of time-varying coefficients\, and
the use of weak-form model selection as a classifier to determine specie
s membership in a heterogeneous population of initially unlabeled cells.
We will conclude with an overview of possible next directions\, includi
ng open questions related to numerical analysis and theoretical recovery
guarantees.\n\n\nTitle: Weak-form sparse identification of differentia

DESCRIPTION:PIMS-Europe (CNRS IRL #3069) is announcing the return of the
PIMS-Europe Fellowships. The goal of this program is to develop and sup
port research collaborations between mathematical scientists at PIMS mem
ber universities and researchers across France. These fellowships will c
hampion a mutual exchange of knowledge and talent while encouraging cros
s-ocean research on the frontline of the mathematical sciences. Fellowsh
ip awardees will receive CAD $5\,000 to facilitate long-term visits to F
rance. All mathematical scientists with faculty positions at PIMS membe
r universities are eligible for the fellowship. PIMS-Europe Fellows are
expected to spend at least two continuous months working on collaborati
ve research in France. PIMS encourages longer visits. Visits must begin
in 2023 and are expected to last at least 2 months. Applications are a
ccepted until October 1\, 2022.\n\n\nLink: https://www.pims.math.ca/news

DESCRIPTION:Knutson and Miller established a connection between the anti
-diagonal Gröbner degenerations of matrix Schubert varieties and the pre
-existing combinatorics of pipe dreams. They used this correspondence to
give a geometrically-natural explanation for the appearance of the comb
inatorially-defined Schubert polynomials as representatives of Schubert
classes. In this talk\, we will describe a similar connection between di
agonal degenerations of matrix Schubert varieties and bumpless pipe drea
ms\, newer combinatorial objects introduced by Lam\, Lee\, and Shimozono
. This connection was conjectured by Hamaker\, Pechenik\, and Weigandt.
This talk is based on joint work with Anna Weigandt.\n\n\n\nSpeaker: Pat

DESCRIPTION:Kinetic equations describe the nonequilibrium dynamics of a
complex system using a probability density function. Despite of their im
portant role in multiscale modeling to bridge microscopic and macroscopi
c scales\, numerically solving kinetic equations is computationally dema
nding as they lie in the six-dimensional phase space. Dynamical low-rank
method is a dimension-reduction technique that has been recently applie
d to kinetic theory\, yet most of the endeavor is devoted to linear or c
ollisionless problems. In this talk\, we introduce efficient dynamical l
ow-rank methods for Boltzmann type collisional kinetic equations\, build
ing on certain prior knowledge about the low-rank structure of the solut
ion.\n\n\nTitle: Dynamical low-rank methods for high-dimensional collis

DESCRIPTION:Numerical simulations of physical or chemical processes in h
eterogeneous \nmedia require a resolution of the heterogeneous structure
. If\, however\, \nthis heterogeneity is microscopically small while the
object under \nconsideration is large\, a dimensional mismatch occurs a
nd classical \nnumerical methods become infeasible.\n\nAt this point\, a
nalytical homogenization provides effective homogeneous \nsubstitute mod
els\, which can be simulated numerically much more easily. One class of
problems that can be treated are processes in porous media. In many bi
ological or chemical applications\, the pore structure evolves \nin time
\, which impedes classical homogenization. By means of the \ntwo-scale t
ransformation method\, we can overcome this difficulty and \nderive new
effective models for problems in evolving heterogeneous media.\n\n\nTitl

DESCRIPTION:Clemens–Griffiths introduced the classical intermediate Jaco
bian obstruction to rationality for complex threefolds\, and used it to
show irrationality of the cubic threefold. Recently\, over non-closed fi
elds\, Hassett–Tschinkel and Benoist–Wittenberg refined this obstruction
using torsors over the intermediate Jacobian. In this talk\, we identif
y these intermediate Jacobian torsors for conic bundle threefolds\, and
we give applications to rationality over non-closed fields. This talk is
based on joint work with S. Frei\, S. Sankar\, B. Viray\, and I. Vogt\,
and on joint work with M. Ji.\n\n\nTitle: Rationality of conic bundle

DESCRIPTION:Naively implemented\, statistical procedures are prone to le
aking information about their training data\, which can be problematic i
f the data is sensitive. Differential privacy\, a rigorous notion of dat
a privacy\, offers a principled framework to dealing with these issues.
I will survey recent results in differential private statistical estimat
ion\, presenting a few vignettes which highlight novel challenges for ev
en the most fundamental problems\, and suggesting solutions to address t
hem. Along the way\, I’ll mention connections to tools and techniques in
a number of fields\, including information theory and robust statistics
. If you are unable to attend in person\, the group is hoping to broadca
st as a Zoom meeting as well. Please contact Kristina at pims@uvic.ca.\n

DESCRIPTION:Resolving a conjecture of Erdos and Turan from the 1930's\,
in the 1970's Szemeredi showed that a set of integers with positive uppe
r density contains arbitrarily long arithmetic progressions. Soon therea
fter\, Furstenberg used Ergodic Theory to gave a new proof of this resul
t\, leading to the development of combinatorial ergodic theory. These to
ols have led to uncovering new patterns that occur in any sufficiently l
arge set of integers\, but until recently all such patterns have been fi
nite. Based on joint work with Joel Moreira\, Florian Richter\, and Dona
ld Robertson\, we discuss recent developments for infinite patterns\, in
cluding the resolution of conjectures of Erdos.\n\n\nTitle: Infinite pa

DESCRIPTION:A basic example of a family of curves with level structure i
s the Hesse pencil of elliptic curves:\n$$x^3+y^3+z^3+ \\lambda xyz = 0\
,$$\nwhich gives a family of elliptic curves with labelled 3-torsion poi
nts. The parameter $\\lambda$ is a parameter on the corresponding moduli
space.\n\nThe analogue for genus 2 curves is given by the Burkhardt qua
rtic threefold. In this talk\, we will go over some of its interesting g
eometric properties. In an arithmetic context\, where one considers a no
n-algebraically closed base field\, it is also important to consider the
different possible twists of the space. We will discuss an interesting
link with a so-called field of definition obstruction that occurs for ge
nus 2 curves\, and see that this obstruction has interesting consequence
s for the existence of rational points on certain twists of the Burkhard
t quartic.\n\nThis talk is based on joint works with my students Brett N
asserden and Eugene Filatov.\n\n\nTitle: Twists of the Burkhardt quartic

DESCRIPTION:The principle of ‘maximum entropy’ states that the probabili
ty distribution which best represents the current state of knowledge abo
ut a system is the one with largest entropy with respect to a given prio
r (data) distribution. It was first formulated in the context of statist
ical physics in two seminal papers by E. T. Jaynes (Physical Review\, Se
ries II. 1957)\, and thus constitutes an information theoretic manifesta
tion of Occam’s razor. We bring the idea of maximum entropy to bear in t
he context of linear inverse problems in that we solve for the probabili
ty measure which is close to the (learned or chosen) prior and whose exp
ectation has small residual with respect to the observation. Duality lea
ds to tractable\, finite-dimensional (dual) problems. A core tool\, whic
h we then show to be useful beyond the linear inverse problem setting\,
is the ‘MEMM functional’: it is an infimal projection of the Kullback- L
eibler divergence and a linear equation\, which coincides with Cramér’s
function (ubiquitous in the theory of large deviations) in most cases\,
and is paired in duality with the cumulant generating function of the pr
ior measure. Numerical examples underline the efficacy of the presented
framework. The talk encompasses joint work with Rustum Choksi (McGill)\,
Ariel Goodwin (McGill)\, Carola-Bibiane Schönlieb (Cambridge)\, and Yak
ov Vaisbourd (McGill).\n\n\nTitle: The Maximum Entropy on the Mean Metho

DESCRIPTION:We present a kinetic version of the Watanabe-Strogatz (WS) t
ransform for vector models in this paper. From the generalized WS-transf
orm\, we can reduce the kinetic vector model into an ODE system. We also
obtain the cross-ratio type constant of motion functionals for kinetic
vector models under suitable conditions. We present the sufficient and n
ecessary conditions for the existence of the suggested constant of motio
n functionals. As an application of the constant of motion functional\,
we provide the instability of bipolar states of the kinetic swarm sphere
model. We also provide the WS-transform and constant of motion function
als for non-identical kinetic vector models.\n\n\nTitle: The Watanabe-S

DESCRIPTION:In this talk I will discuss distribution results for traces
of Frobenius for various families of elliptic curves with respect to the
Lang--Trotter conjecture and extremal primes. These are related to the
work of Sha--Shparlinski on the average Lang--Trotter conjecture for sin
gle-parametric families as well as the work of various authors on the di
stribution of traces of Frobenius for primes in congruence classes. This
is joint work with my former student Nathan Fugleberg.\n\n\nTitle: Dis

DESCRIPTION:Let M be a smooth submanifold of R^n equipped with the Eucli
dean(chordal) metric. This talk will consider the smallest dimension\, m
\, for which there exists a bi-Lipschitz function f:M →R^m with bi-Lipsc
hitz constants close to one. We will begin by presenting a bound for the
embedding dimension m from below in terms of the bi-Lipschitz constants
of f and the reach\, volume\, diameter\, and dimension of M. We will th
en discuss how this lower bound can be applied to show that prior upper
bounds by Eftekhari and Wakin on the minimal low-distortion embedding di
mension of such manifolds using random matrices achieve near-optimal dep
endence on dimension\, reach\, and volume (even when compared against no
nlinear competitors). Next\, we will discuss a new class of linear maps
for embedding arbitrary (infinite) subsets of R^n with sufficiently smal
l Gaussian width which can both (i) achieve near-optimal embedding dimen
sions of submanifolds\, and (ii) be multiplied by vectors in faster than
FFT-time. When applied to d-dimensional submanifolds of R^n we will see
that these new constructions improve on prior fast embedding matrices i
n terms of both runtime and embedding dimension when d is sufficiently s
mall. Time permitting\, we will then conclude with a discussion of non-l
inear so-called “terminal embeddings” of manifolds which allow for exten
sions of the famous Johnson-Lindenstrauss Lemma beyond what any linear m
ap can achieve. This talk will draw on joint work with various subsets
of Mark Roach (MSU)\, Benjamin Schmidt (MSU)\, and Arman Tavakoli (MSU).

DESCRIPTION:In this paper we introduce an apparently new spline-like int
erpolant that we call a compact cubic interpolant or compact cubic splin
e\; this is similar to a cubic spline introduced in 1972 by Swartz and V
arga\, but has higher order accuracy at the edges. We argue that for nea
rly uniform meshes the compact cubic approach offers some potential adva
ntages\, and offers a simple way to treat the edge conditions\, relievin
g the user of the burden of deciding to use one of the three standard op
tions: free (natural)\, complete (clamped)\, or “not-a-knot” conditions.
Finally\, we establish that the matrices defining the compact cubic spl
ines (equivalently\, the fourth-order compact finite difference formulæ)
are totally nonnegative\, if all mesh widths are the same sign\, for in
stance if the mesh is real and nodes are numbered in increasing order.
The talk will be in-person and use chalk\, in the wonderful multi-board
room that SFU has for the purpose. The YouTube version linked above was
a computer version of the same talk\, with slides\, which has some advan
tages (run it at double speed!). But the chalk version offers a chance t
o slow down and appreciate more of the "big picture". The topic will be
accessible if the listener has heard what a "spline" is\, but the main p
oint is to prove total nonnegativity of a certain tridiagonal matrix. I'
ll also make a connection to the (very useful) subject of compact finite
differences. This is joint work with Dr. Leili Rafiee Sevyeri (CS Univ
ersity of Waterloo)\n\n\nTitle: Compact cubic splines and compact finit
