Half canonical rings of Gorenstein spin curves of genus two
arXiv:2312.09671
Abstract
We introduce the notion of generalised Gorenstein spin structure on a curve and we give an explicit description of the associated section ring for curves of genus two with ample canonical bundle, obtaining five different formats.
We added the code file for MAGMA computation. We slightly changed the introduction, we added new subsections in Section 2 and some references following the referee's suggestions
