Enumerative Combinatorics and Related Applications

3:30 PM-6:00 PM
Room: Sidney Smith 1072

This minisymposium focuses on some aspects of enumeration that have been of great value in physics and computer science. The speakers will highlight some of the most recent effective approaches. They will discuss the applications of algebraic combinatorics to sub-atomic physics, the interaction of algebraic combinatorics and quantum gravity, new discoveries relating to enumerative theorems on partitions and exactly solved models in statistical mechanics, and applications of these same methods to problems in computer science.
