Time-dependent one-dimensional electromagnetic wave propagation in inhomogeneous media: exact solution in terms of transmutations and Neumann series of Bessel functions

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…

Spectral parameter power series for arbitrary order linear differential equations

Vladislav V. Kravchenko, R. Michael Porter, Sergii M. Torba

Let be the -th order linear differential operator with variable coefficients. A representation is given for linearly ind…

Spectral problems in inhomogeneous media, spectral parameter power series and transmutation operators

Vladislav V. Kravchenko, Sergii M. Torba

We give a brief overview of recent developments in Sturm-Liouville theory concerning operators of transmutation (transformation) and spectral parameter power series (SPPS) and prop…

Eigenvalue problems, spectral parameter power series, and modern applications

K. V. Khmelnytskaya, V. V. Kravchenko, H. C. Rosu

In the present review we deal with the recently introduced method of spectral parameter power series (SPPS) and show how its application leads to an explicit form of the characteri…

Spatial pseudoanalytic functions arising from the factorization of linear second order elliptic operators

Vladislav V. Kravchenko, Sébastien Tremblay

Biquaternionic Vekua-type equations arising from the factorization of linear second order elliptic operators are studied. Some concepts from classical pseudoanalytic function theor…

Solution of boundary value and eigenvalue problems for second order elliptic operators in the plane using pseudoanalytic formal powers

Raul Castillo Perez, Vladislav V. Kravchenko, Rabindranath Resendiz Vazquez

We propose a method for solving boundary value and eigenvalue problems for the elliptic operator D=divpgrad+q in the plane using pseudoanalytic function theory and in particular ps…
