Title: Homogenization and Inverse Problems.

Abstract: I will review some conditional stability results and recovery algorithms in various inverse problems with irregular coeficients. The arguments use the quasiconformal mappings and a connection with the nonelliptic time dependent Schrodinger equation. Then I will discuss in detail how G-convergence can be utilized to create instabilities in inverse problems. The latter is a work with Y. Kurylev and A. Ruiz. If time allows, I will sketch part of a program with Guijarro, Kurylev and Ruiz to homogenize elliptic equation in paralellizable manifolds.
