DESCRIPTION:Title: <a href="https://researchseminars.org/talk/TQFT/3/">Int
 roduction to foam evaluation</a>\nby Mikhail Khovanov (Columbia University
 ) as part of Topological Quantum Field Theory Club (IST\, Lisbon)\n\n\nAbs
 tract\nFoam evaluation was discovered by Louis-Hardrien Robert and Emmanue
 l Wagner slightly over three years ago. It's a remarkable formula assignin
 g a symmetric function to a foam\, that is\, to a decorated 2-dimensional 
 CW-complex embedded in three-space. We'll explain their formula in the 3-c
 olor case in the context of unoriented foams and discuss its relation to K
 ronheimer-Mrowka homology of graphs and the four-color theorem.\n
