Power-kernel fractional Sturm--Liouville operators: a graph realization and boundary-independent singular-value asymptotics

Niyaz Tokmagambetov

For we construct a closed realization of in whose domain contains the singular mode . The domain, defined via…

Dilation-balanced product Pitt inequalities for mixed-tail potentials

Niyaz Tokmagambetov

Motivated by the one-dimensional and radial theory of general monotone functions, we introduce a natural multiparameter general-monotonicity class for product Fourier inequalities.…

Late-Time Fractional-Order Identification in Caputo Diffusion Equation

Niyaz Tokmagambetov

We study late-time identification of the Caputo order in a linear diffusion equation generated by a strictly positive self-adjoint operator with compact resolvent. For signed scala…

Fractional wave equation with irregular mass and dissipation

Michael Ruzhansky, Mohammed Elamine Sebih, Niyaz Tokmagambetov

In this paper, we pursue our series of papers aiming to show the applicability of the concept of very weak solutions. We consider a wave model with irregular position dependent mas…

One inverse source problem generated by the Dunkl operator

Bayan Bekbolat, Niyaz Tokmagambetov

The aim of this paper is to study time-fractional pseudo-parabolic type equations generated by the Dunkl operator. The forward problem is considered and its well-posedness is estab…

Inverse problem of determining time-dependent leading coefficient in the time-fractional heat equation

Daurenbek Serikbaev, Michael Ruzhansky, Niyaz Tokmagambetov

In this paper, we investigate direct and inverse problems for the time-fractional heat equation with a time-dependent leading coefficient for positive operators. First, we consider…
