英文摘要
Tomari found a sufficient condition for the new 5 classes of hypersurface simple K3 singularities would be the last of 95+5 classes. The four of these 5 classes are the classical one found in the Ishii-Tomari theory on Veronese subring of famous 95 classes, but the other one is completely new one. Watanabe has been studying F-threshold, integral closures, and tight closures of several ideals and got many results.
