Title:
On nefness criterion

Speaker:
Daisuke Matsushita

Abstract:
Let X be a projective variety. A line bundle L on X is said to be nef if L.C \ge 0 for all effective curves C on X. If X is K3 without (-2)-curves, L is nef if L^ 2 \ge 0. If X is K3 with (-2)-curves, L is nef if L.C \ge 0 for all (-2)-curves on X. We extend this propertis for a class of higher dimensional varieties which include IHSMs
