Divisors on surfaces isogenous to a product of mixed type with $p_g=0$

Davide Frapporti and Kyoung-Seog Lee

Vol. 318 (2022), No. 2, 233–247
Abstract

We study effective, nef and semiample cones of surfaces isogenous to a product of mixed type with pg = 0. In particular, we prove that all reducible fake quadrics are Mori dream surfaces.

Keywords
Mori dream space, surface of general type with $p_g=0$, effective cone, nef cone, semiample cone, Cox ring, surface isogenous to a product of mixed type
