Burnaby

• #### Prerequisites:

MATH 340 or 332, and MACM 201 (with a grade of at least B-).

## Description

#### CALENDAR DESCRIPTION:

Design theory: Steiner triple systems, balanced incomplete block designs, latin squares, finite geometries. Enumeration: generating functions. Burnside's Lemma, Polya counting. Quantitative.

#### LEARNING OBJECTIVES:

- Successful students will master a collection techniques for enumerating combinatorial classes of objects with either recursive structure, or internal symmetry.

- Successful students will be able to identify combinatorial structure in mathematical objects from linear algebra and geometry, and they will possess strategies to exploit any underlying balance or symmetry.

- Successful students will be able to identify, and generate combinatorial design structures.

Course Details:

The modern world of combinatorics features a complicated web of amazing structures, many of which have deep connections to other subjects such as group theory, geometry, and algebra.  The goal of this course is to introduce some of these special structures, understand some of their properties, and make connections between them and to other areas of math.  Here is a taste of what we will discover:

• Systematic strategies for enumerating combinatorial classes, including Polya counting and generating functions
• Lattices and posets
• Combinatorial aspects of polytopes
• The projective line, Finite geometries, projective and affine.
• Steiner systems, block designs.

• Assignments (6 assignments, equally weighted) 30%
• Midterm 20%
• Final Exam 50%

#### Registrar Notes:

SFU’s Academic Integrity web site http://www.sfu.ca/students/academicintegrity.html is filled with information on what is meant by academic dishonesty, where you can find resources to help with your studies and the consequences of cheating.  Check out the site for more information and videos that help explain the issues in plain English.

Each student is responsible for his or her conduct as it affects the University community.  Academic dishonesty, in whatever form, is ultimately destructive of the values of the University. Furthermore, it is unfair and discouraging to the majority of students who pursue their studies honestly. Scholarly integrity is required of all members of the University. http://www.sfu.ca/policies/gazette/student/s10-01.html
