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 complex potentials
Vladislav V. Kravchenko
An approach for solving a variety of inverse coefficient problems for the Sturm-Liouville equation -y''+q(x)y=λy with a complex valued potential q(x) is presented. It is based on N…
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…
Schrödinger equation with finitely many -interactions: closed form, integral and series representations for solutions
Vladislav V. Kravchenko, Víctor A. Vicente-Benítez
A closed form solution for the one-dimensional Schrödinger equation with a finite number of -interactions \[ \mathbf{L}_{q,\mathfrak{I}_{N}}y:=-y^{\prime\prime}+\left( q(x)+\sum…
