Automorphism group of Batyrev Calabi-Yau threefolds
Published 15 Sep 2011 in math.AG and math.SG | (1109.3238v2)
Abstract: In this paper, we will prove that all Batyrev Calabi-Yau threefolds, arising from a small resolution of a generic hyperplane section of a reflexive Fano-Gorenstein fourfold, have finite automorphism group. Together with Morrison conjecture, this suggests that Batyrev Calabi-Yau threefolds should have a polyhedral Kahler (ample) cone.
