Intersection cohomology of higher rank Teichmüller components
Mathieu Ballandras, Oscar García-Prada
Exploiting the non-abelian Hodge correspondence, together with the Cayley correspondence, in this paper, we compute the intersection cohomology of certain singular higher rank Teic…
Comet-shaped quiver varieties, Weyl group actions, and modified Kostka polynomials
Mathieu Ballandras
We study an algebra spanned by modified Kostka polynomials. Particular structure coefficients of this algebra are interpreted as traces of some Weyl group actions on the intersecti…
Intersection cohomology of character varieties for punctured Riemann surfaces
Mathieu Ballandras
We study intersection cohomology of character varieties for punctured Riemann surfaces with prescribed monodromies around the punctures. Relying on previous result from Mellit for…
Trivializations of moment maps
Mathieu Ballandras
We study various trivializations of moment maps. First in the general framework of a reductive group acting on a smooth affine variety. We prove that the moment map is a locall…
