Quasi-Trefftz spaces for a first-order formulation of the Helmholtz equation
Lise-Marie Imbert-Gérard, Andréa Lagardère, Guillaume Sylvand +1
This work is concerned with the development of quasi-Trefftz methods for first-order differential systems. It focuses on discrete quasi-Trefftz spaces, starting from their definiti…

Extension of the G{ü}nter derivatives to Lipschitz domains and application to the boundary potentials of elastic waves
A. Bendali, S Tordeux
The scalar G{ü}nter derivatives of a function defined on the boundary of a three-dimensional domain are expressed as components (or their opposites) of the tangential vector rotati…

Self-adjoint curl operators
R. Hiptmair, P. R. Kotiuga, S. Tordeux
We study the exterior derivative as a symmetric unbounded operator on square integrable 1-forms on a 3D bounded domain . We aim to identify boundary conditions that render this…
