Abstract:

This is an overview talk on the usage of foams, which are cobordisms with singularities, in the construction of some categories used to obtain link homology theories.

In this talk I will explain how foams can be interpreted in terms of higher representation theory as categorifications of the spaces of intertwiners between tensor representations of quantum groups and how to obtain them from the so-called trivalent TQFTs.

Some explicit examples will be provided.
