Resumen de Intersection cohomology of the Uhlenbeck compactification of the Calogero–Moser space

Michael Finkelberg, Victor Ginzburg, Andrei Ionov, Alexander Kuznetsov

• 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 the Uhlenbeck compactification. We use the resolution to compute the stalks of the IC-sheaf of the Uhlenbeck compactification.
