FEM-BEM coupling for the high-frequency Helmholtz problem

Jens Markus Melenk, Ilaria Perugia, Alexander Rieder

We present a wavenumber-explicit analysis of FEM-BEM coupling methods for time-harmonic Helmholtz problems proposed in arXiv:2004.03523 for conforming discretizations and in arXiv:…

FEM-BEM coupling in Fractional Diffusion

Markus Faustmann, Alexander Rieder

We derive and analyze a fully computable discrete scheme for fractional partial differential equations posed on the full space $R^{d}$ . Based on a reformulation using the w…

Fractional Diffusion in the full space: decay and regularity

Markus Faustmann, Alexander Rieder

We consider fractional partial differential equations posed on the full space $R^{d}$ . Using the well-known Caffarelli-Silvestre extension to $R^{d} \times R^{+}$ as equivalent defini…
