Local volumes |
Abstract |
Given a normal variety X of dimension at least two, we fix a point x on it and define a volume over x for any Cartier divisor on an arbitrary birational model dominating X. This volume function can be used to define and study a notion of volume for a normal isolated singularity that is a generalization of a volume introduced by J. Wahl for surface singularities. We also compare our volume of isolated singularities to a different recent generalization of Wahl’s work, as introduced by S.Boucksom, T. de Fernex and C. Favre. |
