Cauchy problem for a second-order hyperbolic operator-differential equation with a singular coefficient

In a Hilbert space, we study the well-posedness of the Cauchy problem for a second-order operator-differential equation with a singular coefficient.     

Asymptotic behavior of the eigenvalues of a boundary-value problem for a second-order elliptic operator-differential equation

We study the asymptotic behavior of the eigenvalues of a boundary-value problem with spectral parameter in the boundary conditions for a second-order elliptic operator-differential equation. The asymptotic formulas for the eigenvalues are obtained. __________ Translated from Ukrains’kyi Matematychnyi Zhurnal, Vol. 58, No. 8, pp. 1146–1152, August, 2006.

A new constructive method for solving singular integral equations

In this paper, a new method for the approximate solution of linear singular integral equations defined on smooth closed curves is proposed and justified.     

The radiativeK* meson decays in QCD

ThegK ^o* K ^o _γ andgK ^+* K ⁺ _γ coupling constants and the radiative decay widths are calculated in the context of QCD sum rules. It is found that the discrepancy between the experimental data and theoretical results still exists.
