主 题：quadric threefold hypersurface section stability geometric invariant theory
摘 要：Let S be a complete intersection of a smooth quadric 3-fold Q and a hypersurface of degree d in *** analyze GIT stability of S with respect to the natural G=SO(5,C)-*** prove that if d 4 and S has at worst semi-log canonical singularities then S is ***,we prove that if d 3 and S has at worst semi-log canonical singularities then S is G-semistable.
