DESCRIPTION:Speaker: Márton Hablicsek\nhosted by Tamas Hausel\nAbstract: L
 et $X$ be an oriented closed connected surface. The set of group represent
 ations from the fundamental group of $X$ to an algebraic group $G$ has a s
 tructure of an algebraic variety. This variety is called the $G$-represent
 ation variety of $X$. In this talk\, I will use a geometric method develop
 ed by González-Prieto\, Logares\, Muñoz\, and Newstead to compute the v
 irtual classes of $G$-representation varieties where $G$ is the group of c
 omplex upper-triangular matrices of rank 2\, 3\, or 4. This is joint work 
 with Jesse Vogel.
