Mihai Fulger : Positive cones of numerical cycle classes , 399-415

Abstract:

We survey recent results on positive cones of numerical cycle classes. The original contribution is a class of singular examples: projective cones from a point over embedded projective varieties, and a relative version of this.

Key Words: convex cones, positive cycles, numerical classes, affine cone.
