Intersection cohomology of the Uhlenbeck compactification of the Calogero-Moser space

Selecta Mathematica, New Series. 2016. Vol. 22. No. 4. P. 2491-2534.

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.
