DESCRIPTION:Title: <a href="https://researchseminars.org/talk/rlgts/8/">Fr
 om SL(2) to GL(N) foam evaluation</a>\nby Mikhail Khovanov (Columbia Unive
 rsity) as part of Regensburg low-dimensional geometry and topology seminar
 \n\n\nAbstract\nFoams in 3-space are cobordisms between planar graphs that
  are heavily used in link homology theories. In this talk we'll explain ho
 w foam theory can be built from the ground up starting with an evaluation 
 of closed foams\, for SL(2) foams\, then GL(2) foams\, and finally GL(N) f
 oams for any N. The talk is based on joint work with Louis-Hadrien Robert 
 and on L.-H. Robert and Emmanuel Wagner's work on foam evaluation.\n
