Intersection cohomology of the Uhlenbeck compactification of the Calogero-Moser space
Michael Finkelberg, Victor Ginzburg, Andrei Ionov +1
We study the natural Gieseker and Uhlenbeck compactifications of the rational Calogero-Moser phase space. The Gieseker compactification is smooth and provides a small resolution of…

Supersymmetric Semisimple Cardy-Frobenius Algebras
A. Ionov
Cardy-Frobenius algebra is the algebraic structure on the space of states in open-closed topological field theory. We prove that every semisimple super Cardy-Frobenius algebras is…
