Boundary integral equations in space and time: Higher order Galerkin methods and applications

Vortrag von Prof. Dr. Heiko Gimperlein

Datum: 27.09.23  Zeit: 16.30 - 17.30  Raum: ETH HG E 1.2

Boundary integral formulations are well-​known to lead to efficient numerical methods for time-​independent scattering and emission problems. In this talk we consider corresponding formulations for the time-​dependent acoustic and elastic wave equations. We survey recent work on space-​time Galerkin methods for the numerical solution, including higher order approximations by h- and hp-​versions, a posteriori error estimates and adaptive mesh refinements, and illustrate them for applications in traffic noise.
