POTSI/Mprime Talk in Analysis

We study the convex hull of the intersection between a convex set E (obtained by intersecting a convex cone with an affine set) and a linear disjunction. This intersection is at the core of solution techniques for Mixed Integer Conic Optimization. We prove that, if a cone K (resp. a cylinder C) exist that has the same intersection with the frontier of the disjunction as E, then the convex hull is obtained by intersecting E with K (resp. C).

I will show that a magnetic Schrodinger operator can be determined from certain partial measurements of its Dirichlet-Neumann map. I will explain the result and its context, and give a short sketch of the proof.

We welcome Dr. Vladimir Zubov from the Southern Federal University in Russia, who will be speaking on numerical modeling of a convection-diffusion problem in radioactive pollution (a numerical partial differential equation problem).

In this talk I will discuss local well-posedness of an Initial Value problem associated to a system of PDE's generalizing the Korteweg-de Vries Equation (KdV).  I will discuss several approaches to the KdV-type problems emphasizing the energy method and local smoothing estimates that are essential to my proof.

The Pseudodifferential Operator Theory and Seismic Imaging research group (POTSI) at Calgary invites you to another talk in the POTSI/Mprime series in Analysis.   This coming Tuesday,  we welcome Dr Christos Chorianopoulos from the National Technical University iin Greece, who will be speaking on numerical range for matrices and matrix polynomials.
