Spectral density in a Moszynski's class of Jacobi matrices
Eduard Ianovich
In this paper it is considered a spectral density for a class of Jacobi matrices with absolutely continuous spectrum that was examined first by Moszynski. It is shown that the corr…
Spontaneous decay of level from spectral theory point of view
E. A. Ianovich
In quantum field theory it is believed that the spontaneous decay of excited atomic or molecular level is due to the interaction with continuum of field modes. Besides, the atom ma…
On one condition of absolutely continuous spectrum for self-adjoint operators and its applications
Eduard Ianovich
In this work the method of analyzing of the absolutely continuous spectrum for self-adjoint operators is considered. For the analysis it is used an approximation of self-adjoint op…
Jacobi matrices: continued fractions, approximation, spectrum
Eduard Ianovich
In this work the spectral theory of self-adjoint operator represented by Jacobi matrix is considered. The approach is based on the continued fraction representation of the reso…
