Synthesis of a quantum tree Weyl matrix

Sergei A. Avdonin, Kira V. Khmelnytskaya, Vladislav V. Kravchenko

A method for successive synthesis of a Weyl matrix (or Dirichlet-to-Neumann map) of an arbitrary quantum tree is proposed. It allows one, starting from one boundary edge, to comput…

Reconstruction techniques for quantum trees

Sergei A. Avdonin, Kira V. Khmelnytskaya, Vladislav V. Kravchenko

The inverse problem of recovery of a potential on a quantum tree graph from Weyl's matrix given at a number of points is considered. A method for its numerical solution is proposed…

Recovery of a potential on a quantum star graph from Weyl's matrix

Sergei A. Avdonin, Kira V. Khmelnytskaya, Vladislav V. Kravchenko

The problem of recovery of a potential on a quantum star graph from Weyl's matrix given at a finite number of points is considered. A method for its approximate solution is propose…

A representation of the transmutation kernels for the Schrödinger operator in terms of eigenfunctions and applications

Kira V. Khmelnytskaya, Vladislav V. Kravchenko, Sergii M. Torba

The representations of the kernels of the transmutation operator and of its inverse relating the one-dimensional Schrödinger operator with the second derivative are obtained in ter…

Modulated electromagnetic fields in inhomogeneous media, hyperbolic pseudoanalytic functions and transmutations

Kira V. Khmelnytskaya, Vladislav V. Kravchenko, Sergii M. Torba

The time-dependent Maxwell system describing electromagnetic wave propagation in inhomogeneous isotropic media in the one-dimensional case reduces to a Vekua-type equation for bico…
