TITLEDual Complex of Fano Carieties and an Application to Vanishing of Witt Vector Cohomology

ABSTRACT I will explain that the dual complex of a log Fano pair is simply connected. As a corollary, we can get a vanishing theorem of Witt vector cohomology for log canonical Fano threefolds. This is an analogy of the Ambro-Fujino vanishing theorem in characteristic zero.
