Combinatorial Methods for Statistical Physics Models
Special Topics Course, Winter 1999
Many fundamental questions in statistical mechanics are inherently
combinatorial. We will introduce some basic models and examine
natural physical questions from a combinatorial perspective, including
the Ising model, the Potts model, monomer-dimer systems, self-avoiding
walks and percolation theory. Some highlights of the course will
include the Peierls argument (for the Ising model), Kasteleyn's theorem
(for dimer systems), the FKG inequality, and Reimer's new generalization
of the BK inequality (both used in percolation theory).
This course is intended to be introductory and no background in
statistical mechanics is required.
Time: Tuesday and Thursday 2-3:30 (tentatively).
Prerequisites: Some background in combinatorics and probability.
