Positive cones of dual cycle classes

Mihai Fulger, Brian Lehmann

We study generalizations for higher codimension cycles of several well-known definitions of the nef cone of divisors on a projective variety. These generalizations fix some of the…

Kernels of numerical pushforwards

Mihai Fulger, Brian Lehmann

Let $π : X \to Y$ be a morphism of projective varieties and consider the pushforward map $π_{*} : N_{k} (X) \to N_{k} (Y)$ of numerical cycle classes. We show that when the Chow groups of po…
