This article presents a brief survey devoted to the interplay between diffraction and operator theory, particularly between the so-called canonical diffraction problems (exemplified by Sommerfeld half-plane problems) on one hand and operator factoris

This work is devoted to the analysis of the mixed impedance-Neumann-Dirichlet boundary value problem (MIND~BVP) for the Laplace-Beltrami equation on a compact smooth surface $\mathcal{C}$ with smooth boundary. We prove, using the Lax-Milgram Lemma, t

The aim of this work is to present criteria for the equivalent reduction of general Wiener–Hopf operators \( W \,=\,P_{2}A|{P_{1} X}\, \text{where}\, X, Y\) are Banach spaces, \( P_{1}\,\in\,\mathcal{L}(X) , P_{2}\,\in\,\mathcal{L}(Y)\) are any pro

Convolution type operators with symmetry appear naturally in boundary value problems for elliptic PDEs in symmetric or symmetrizable domains. They are defined as truncations of translation invariant operators in a scale of Sobolev-like spaces that ar

It happened on the 7th February 1989 in Karl-Marx-Stadt (KMS) when we met for the first time, a day which I remember with emotion. Somehow Albrecht reminded me on August den Starken (Augustus II the Strong, Elector of Saxony and King of Poland, 1670
