Quasi-Trefftz spaces for a first-order formulation of the Helmholtz equation
By: Lise-Marie Imbert-Gérard , Andréa Lagardère , Guillaume Sylvand and more
Potential Business Impact:
Makes math problems with moving parts easier to solve.
This work is the first step in the development of quasi-Trefftz methods for first-order differential systems. It focuses on discrete quasi-Trefftz spaces, starting from their definition and including construction of corresponding bases together with their computational aspect.
