Normal stable degenerations of Noether-Horikawa surfaces
Abstract
We classify all normal stable Horikawa surfaces with only Q-Gorenstein smoothable log canonical singularities. Furthermore, we provide a criterion for their global Q-Gorenstein smoothability and describe the boundary strata of the moduli space of Q-Gorenstein smoothable normal stable Horikawa surfaces.
