The Kuranishi map for vector bundles on certain products of curves
arXiv:2006.04965 · doi:10.1016/j.topol.2022.108056
Abstract
We describe deformations of vector bundles on surfaces that are a product of two smooth projective curves. We explicitly describe the Kuranishi map around unstable vector bundles and compare the homologies of the Kuranishi spaces of stable and unstable deformations.
