Title:
Foam Evaluation and its Uses in Categorification and Representation Theory
Speaker:
Abstract:
I'll explain the foam evaluation formula due to Louis-Hadrien Robert and Emmanuel Wagner and show how it's used to construct state spaces of planar graphs. These state spaces categorify networks of intertwiners between exterior powers of representations of quantum sl(N) and used to build link homology theories. The limiting case of this theory can be used to recover the category of Soergel bimodules, via disk-like foams in 3-space.
