Singularities of varieties admitting an endomorphism (by a paper of Broustet and Horing) E. Gorinov M. V. Lomonosov Moscow State University, Faculty of Mechanics and Mathematics
Abstract: We define a volume of an isolated singularity $(X,O)$. For every finite morphism of isolated singularity we relate volumes of singularities. If $X$ is $\mathbb Q$-Gorenstein then $Vol(X,O)=0$ iff $X$ has lc singularities.
