Totaro's cone conjecture for klt Calabi–Yau pairs
Totaro's cone conjecture for klt Calabi–Yau pairs
Let be a -factorial projective klt Calabi–Yau pair, meaning that is normal, is an effective -divisor, is -Cartier, and is numerically trivial. Let be the effective nef cone, and let be the effective movable cone.
Totaro's cone conjecture. There exists a rational polyhedral cone that is a fundamental domain for the action of on , namely
with unless . There also exists a rational polyhedral cone that is a fundamental domain for the action of on .
This is a generalized Morrison–Kawamata cone conjecture for klt Calabi–Yau pairs, concerning the effective nef and movable cones rather than the full cones. The source attributes the formulation to Totaro and does not state a resolution here.
