Balanced line bundles on Fano varieties
Brian Lehmann, Sho Tanimoto, Yuri Tschinkel
A conjecture of Batyrev and Manin relates arithmetic properties of varieties with ample anticanonical class to geometric invariants; in particular, counting functions defined by me…

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 be a morphism of projective varieties and consider the pushforward map of numerical cycle classes. We show that when the Chow groups of po…
