April 29, 2014Title: The Geometry of Hypergraphs The work of Linial, London and Rabinovich on the Geometry of Graphs has had a significant and longlasting impact on combinatorial optimization and data analysis. They showed how the mathematics of metric embedding could help solve difficult computational problems, adding some powerful techniques to the algorithm designer's toolkit. I will show how much of this theory extends seemlessly to diversities, a simple generalization of metric spaces beyond pairwise comparisons. The concept of a diversity arose from an unlikely blend of phylogenetics, metric geometry and category theory, and has generated a rich theory which we are only just beginning to explore. I'll talk about our results in diversity embeddings and how diversities provide the natural geometry of hypergraphs.

May 5, 2014Sr. Supervisor: Marni Mishna Title: Variants of the Kernel Method for Lattice Path Models Abstract: The kernel method has proved to be an extremely versatile tool for exact and asymptotic enumeration. Recent applications in the study of lattice walks have linked combinatorial properties of a model to algebraic conditions on its generating function, demonstrating how to extract additional information from the process. This thesis details two new results. In the first, we apply the iterated kernel method to determine asymptotic information about a family of models in the quarter plane, finding their generating functions explicitly and classifying them as non Dfinite. The second considers ddimensional walks restricted to an octant whose step sets are symmetric over every axis. A generalized version of the orbit sum method allows for a representation of their generating functions as diagonals of multivariate rational functions, proving they are Dfinite. In combination with current developments from analytic combinatorics in several variables, this yields dominant asymptotics for all such models.
