### Lipschitz stability of an inverse problem for the Helmholtz equation

Seminar Room 1, Newton Institute

#### Abstract

Consider the inverse problem of determining the potential q from the Neumann-to-Dirichlet map q of a Schrödinger type equation.A relevant question, specially in applications, is the stability of the inversion. In this work, a Lipschitz type stability is established assuming a priori that q is piecewise constant with a bounded know number of unknown values.
