Jyväskylä Inverse Problems Seminar
Jyväskylä Inverse Problems Seminar
The Inverse problems group at the University of Jyväskylä organizes a (roughly) weekly seminar. Please write to giovanni.g.covi@jyu.fi in order to be added to the newsletter, and never miss a seminar again!
Inverse problems are a branch of mathematics with both pure and applied aspects. In physics, engineering and other sciences, the focus usually lies in inferring effects from causes, i.e. in solving a so-called forward problem. What is inverted in an inverse problem is the causality: When we consider an inverse problem, we start with partial knowledge of the result (and perhaps of the causes), and our objective is to infer more about its causes.
The Jyväskylä Inverse Problem Seminar (JIPSem) is a series of lectures organized at the University of Jyväskylä by the Inverse Problems research group.
We discuss mainly pure mathematics. Examples include geometric inverse problems, inverse problems for PDEs, X-ray and electrical impedance tomography, and many more. Read more about our research at this webpage.
Besides our own members, we often host visiting scholars as speakers.

Title: The infinitesimal Steklov inverse problem
Abstract: The Steklov spectrum of a smooth compact Riemannian manifold with boundary is the set of eigenvalues, counted with multiplicities, of its Dirichlet-to-Neumann map. A celebrated question in spectral geometry, known as the “Steklov inverse problem”, asks whether it is possible to recover the metric from its Steklov spectrum, up to a natural gauge. In this talk, we will introduce an interesting version of this inverse problem involving the study of Steklov isospectral deformations, namely one-parameter Riemannian metrics that preserve the Steklov spectrum. We shall present some recent positive results obtained under certain dynamical assumptions on the boundary of the manifold, using methods from hyperbolic dynamics, geometry, and microlocal analysis. This is part of an ongoing project with Sebastián Muñoz Thon (Université Paris-Saclay, France).

Title: AI tools for our group
Abstract: Our group has free access to powerful AI tools for Anthropic. I will show how to access and use these tools. We can then discuss all matters concerning AI in your work.
