Se informa a la comunidad UNL la realización de la charla “Computational Methods for Inverse Problems”, a cargo de Mohsen Tadi.

El evento tendrá lugar el viernes 3 de mayo, 15:30 horas, en el Instituto de Matemática Aplicada del Litoral "Dra. Eleonor Harboure" - UNL - CONICET

Resumen

In this presentation, we discuss a number of methods that can be used for inverse problems involving elliptic systems. The focus of the talk is on methodologies that can be used for various systems. We consider both Cauchy problems and inverse material identification problems. Cauchy problems appear in cases where information at part of the boundary is missing. Both classes of problems are severly ill-posed. In particular, we discuss a method based on multiple forward solution, a method based on proper solution space and methods based on sampling functions. We also present a new result for the inverse Helmholz problem. We apply these methods to problems in heat conduction or Laplace equation, and Helmholtz equation. The first two methods can also be applied to parabolic problems but will not be discussed in this talk. I will also discuss some advantages/disadvantages of some of these methods. In closing, I will discuss my current research efforts in other areas of applied mathematics and some open problems.
