Durfee's conjecture on the signature of smoothings of surface singularities
Tommaso de Fernex, János Kollár, András Némethi
In 1978 Durfee conjectured various inequalities between the signature and the geometric genus of a normal surface singularity. Since then a few counter examples have been found and…
Terminal valuations and the Nash problem
Tommaso de Fernex, Roi Docampo
Let X be an algebraic variety of characteristic zero. Terminal valuations are defined in the sense of the minimal model program, as those valuations given by the exceptional diviso…
Comparing multiplier ideals to test ideals on numerically Q-Gorenstein varieties
Tommaso de Fernex, Roi Docampo, Shunsuke Takagi +1
We show that the reduction to positive characteristic of the multiplier ideal in the sense of de Fernex and Hacon agrees with the test ideal for infinitely many primes, assuming th…
