Algebraic convergence analysis for the Interface Control Domain Decomposition (ICDD) method
Marco Discacciati, Paola Gervasio, Alfio Quarteroni
We develop the convergence analysis of the Interface Control Domain Decomposition (ICDD) method, an overlapping domain decomposition method based on an optimal control framework wi…

On the wave equation with space dependent coefficients: singularities and lower order terms
Marco Discacciati, Claudia Garetto, Costas Loizou
This paper complements the study of the wave equation with discontinuous coefficients initiated in \cite{DGL:22} in the case of time-dependent coefficients. Here we assume that the…
Inhomogeneous wave equation with -dependent singular coefficients

Ahmed R. Tarkhany, Marco Discacciati, Joseph J. Betouras
We present a theoretical study of the onset of electric polarization close to a surface in magnetic materials and in thin films and multilayers. We consider two different paths tha…
