Abstract:

The Noether-Fano inequalities are a classical tool in birational geometry, which describe how a birational map of Fano varieties creates singular linear systems of divisors. In this talk, we provide a general form of the Noether-Fano inequalities which can in particular be applied to a local setting as well. These provide a numerical description of singular divisors obtained by examining two distinct prime blowups of a singularity.
