Title: Connectivity and structure in matroids
Speaker: Stefan van Zwam, Louisiana State University
Abstract: A general theme in matroid structure theory is that highly connected matroids exhibit more structure than matroids with low-order separations. We will discuss several examples of this phenomenon, as well as an application to the theory of error-correcting codes.

Colloquium-Some almost sharp scattering results for the cubic nonlinear wave equation
Tuesday, 1/31/2017, 8:00pm - 11:59pm
Title: Some almost sharp scattering results for the cubic nonlinear wave equation
Speaker: Benjamin Dodson, John Hopkins University
Date and Time: Tuesday, January 31, 2017, 3:00-4:00pm
Place: Rome 771
Tuesday, 1/31/2017, 8:00pm - 11:59pm
Title: Some almost sharp scattering results for the cubic nonlinear wave equation
Speaker: Benjamin Dodson, John Hopkins University
Abstract: In this talk we will discuss some scattering results for the cubic nonlinear wave equation. We will prove these results for radial data nearly lying in the critical Sobolev space. We prove this using hyperbolic coordinates.
