KSB stability is automatic in codimension 3
arXiv:2304.09009
Abstract
KSB stability holds at codimension 1 points trivially, and it is quite well understood at codimension 2 points, since we have a complete classification of 2-dimensional slc singularities. We show that it is automatic in codimension 3.
