We consider an impedance boundary‐value problem for the Helmholtz equation which models a wave diffraction problem with imperfect conductivity on a union of strips. Pseudo‐differential operators acting between Bessel potential spaces and Besov sp

Exterior Dirichlet problems for two-dimensional lattice waves on the semi-infinite triangular lattice are considered. Namely, we study Dirichlet problems for the two-dimensional discrete Helmholtz equation in a plane with a hole. New results are obta

We investigate screen type mixed boundary value problems for anisotropic pseudo-Maxwell’s equations. We show that the problems with tangent traces are well posed in tangent Sobolev spaces. The unique solvability results are proven based on the pote

We investigate screen-type boundary value problems for anisotro-pic pseudo-Maxwell’s equations. It is shown that the problems with tangent traces are well posed in tangent Sobolev spaces. The unique solvability result is then obtained by using a po

We study exterior Dirichlet problems for the two-dimensional discrete Helmholtz equation with the real wave number $$k\in (0,2\sqrt{2})\backslash \{2\}$$ . The investigation is carried out without passing to the complex wave number. Similarly to the

The present paper is devoted to the study of the effective properties of 2D unbounded composite materials with temperature dependent conductivities. We consider a special case of nonlinear composites, when the conductivity coefficients of the matrix
