SUMMARY:On the behavior of F-signature on the Nef cone
DESCRIPTION:Speaker: Seungsu Lee\, University of Utah\n\nF-signature plays a crucial role when measuring singularities of varieties in positive characteristics. For example, if R is a local ring, s(R) = 1 implies R is regular, and 0 < s(R) < 1 implies R is strongly F-regular which is a char p analog of klt singularities. For a globally F-regular variety …
