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: From source-to-solution map to distance data to geometry
Abstract: Continuing from the previous talk, the boundary control method will be extended to a higher-dimensional Riemannian manifold setting, where the measurement operator is a local source-to-solution map associated with the wave equation. The unique determination of the manifold from the measurement operator is established in two steps: first, it is shown that the measurement operator determines the so-called distance data; second, it is shown that the distance data determines the geometric structure of the manifold. The presentation is based on the article "Correlation based passive imaging with a white noise source" by Helin, Lassas, Oksanen, and Saksala (2018).
