Gulbrandsen-Halle-Hulek degeneration and Hilbert-Chow morphism
arXiv:1709.01240
Abstract
For a semistable degeneration of surfaces without a triple point, we show that two models of degeneration of Hilbert scheme of points of the family, Gulbrandsen-Halle-Hulek degeneration given in [GHH] and the one given by the author in [N], are actually isomorphic.
