      Elisa PRATO - Nonrational symplectic toric reduction and cutting.

      Résumé : In this talk, I will discuss generalizations of the symplectic reduction and symplectic cutting operations to the context of nonrational toric geometry (joint work with F. Battaglia). Some examples and applications will be examined.[

      Miguel Fernández Duque - Local uniformization of codimension one foliations

      Résumé : In 1940 O. Zariski obtained Local Uniformization on algebraic varieties. Using this result, which is true in arbitrary dimension, in 1944 he obtained Resolution of Singularities in dimension three. It was twenty years later, in 1964, when H. Hironaka published his celebrated paper obtaining Resolution of Singularities in any dimension. In the case of codimension one foliations, we only know reduction of singularities results in lower dimensions. In fact, only in dimension two (A. Seidenberg 1968) and three (F. Cano 2004). Following the ideas of Zariski, in this talk we present the result of Local Uniformization for codimension one foliations defined in ambient spaces of arbitrary dimension. This is a joint work with F. Cano.[
