$L_{p} \to L_{q}$ boundedness of Fourier multipliers

Medet Nursultanov

We investigate the $L_{p} \mapsto L_{q}$ boundedness of the Fourier multipliers. We obtain sufficient conditions, namely, we derive Hormander and Lizorkin type theorems. We also obtain…

Asymptotic expansion for the eigenvalues of a perturbed anharmonic oscillator

Ksenia Fedosova, Medet Nursultanov

In this article, we study the spectral properties of the perturbation of the generalized anharmonic oscillator. We consider a piecewise Hölder continuous perturbation and investiga…
