Uniruledness of stable base loci of adjoint linear systems with and without Mori Theory
arXiv:0902.1142
Abstract
We explain how to deduce from recent results in the Minimal Model Program a general uniruledness theorem for base loci of adjoint divisors. We also show how to recover special cases by extending a technique introduced by Takayama.
