Analysis and improvement of a semi-Lagrangian exponential scheme for the shallow-water equations on the rotating sphere
João Guilherme Caldas Steinstraesser, Martin Schreiber, Pedro da Silva Peixoto
In this work, we study and extend a class of semi-Lagrangian exponential methods, which combine exponential time integration techniques, suitable for integrating stiff linear terms…

High-order exponential integration for seismic wave modeling
Fernando V. Ravelo, Martin Schreiber, Pedro S. Peixoto
Seismic imaging is a major challenge in geophysics with broad applications. It involves solving wave propagation equations with absorbing boundary conditions (ABC) multiple times.…
