Fast Solution Methods for Wave Propagation Problems: From Classical Domain Decomposition Solvers to Learning

Wave propagation and scattering problems are of huge importance in many applications in science and engineering – e.g., in seismic and medical imaging and more generally in acoustics and electromagnetics. Large-scale simulations of those applications are one of the hard problems from a computational point of view since requires an interplay between the parsimonious but sufficiently accurate discretisation methods and more sophisticated solution methods. Our aim is to show on one side, how classical domain decomposition methods developed in the latest years coupled with carefully chosen discretisations can help in this endeavour. On the other side, we would like to propose some openings towards the very attractive package of approximation-solution-optimisation offered by the new methods in scientific machine learning.

Direct and Inverse problems in heart muscle fibers identification

I present some exact and approximate solutions of weak harmonic maps in two and three dimensions for the nonlinear Frank-Oseen equations from liquid crystal theory and

their possible applications in the framework of non-invasive identification of the direction of muscle

fibers in the human heart, as well as their striking similarity to certain structures in the field of astrophysics.

It is a collaborative work with Nicolás Barnafi (PUC, Chile).
