Title: Colloquium: Global existence results for the Surface Quasi-geostrophic equations (SQG)

Abstract: There has been high scientific interest to understand the behavior of the SQG equation because it is a possible model to explain the formation of fronts of hot and cold air. In a different direction P. Constantin, A. Majda and E. Tabak (1994) proposed this system as a 2D model for the 3D vorticity intensification and showed that there is a geometric and analytic analogy with 3D incompressible Euler equations. It is not known at this moment if this equation can produce singularities. In this lecture I will discuss some recent work, joint with Angel Castro, Javier Gomez-Serrano and Alex Ionescu, on the existence of non trivial families of global solutions of the inviscid surface quasi-geostrophic equation.

Student/Postdoc Working Geometry Seminar

Time: 5:00PM - 6:00PM

Location: BLOC 628

Speaker: E. Ventura, TAMU

Title: Hyperdeterminants of special format

Abstract: We discuss a classical method to compute hyperdeterminants of special format due to Schafli, and some connections to real typical ranks.
