A Localization Principle for Orbifold Theories
Tommaso de Fernex, Ernesto Lupercio, Thomas Nevins +1
In this article, written primarily for physicists and geometers, we survey several manifestations of a general localization principle for orbifold theories such as -theory, inde…
Length, multiplicity, and multiplier ideals
Tommaso de Fernex
Let (R,m) be an n-dimensional regular local ring, essentially of finite type over a field of characteristic zero. In this paper we study the relationship between the singularities…
Bad loci of free linear systems
Tommaso de Fernex, Antonio Lanteri
The bad locus of a base-point free linear system L on a normal complex projective variety X is defined as the subset B(L) of X of points that are not contained in any irreducible a…
Stringy Chern classes of singular varieties
Tommaso de Fernex, Ernesto Lupercio, Thomas Nevins +1
Motivic integration and MacPherson's transformation are combined in this paper to construct a theory of "stringy" Chern classes for singular varieties. These classes enjoy strong b…
