March 5
Gene B. Kim (University of Southern California): Distribution of descents in matchings.
Abstract:

The distribution of descents in certain conjugacy classes of  Sn  have been previously studied, and it is shown that its moments have interesting properties. This talk provides a bijective proof of the symmetry of the descents and major indices of matchings (also known as fixed point free involutions) and uses a generating function approach to prove an asymptotic normality theorem for the number of descents in matchings.

Jorge Chavez-Salas: Fuzzy logic fundamentals.
Abstract:

The fundamental concepts and results of fuzzy logic theory will be introduced from an algebraic and logical point of view, and a very simple but original application to human behavior (mathematical psychology or cognitive science in this case) will be presented.
