Parabolic Equations with Singular Coefficients and Boundary Data: Analysis and Numerical Simulations

Arshyn Altybay, Alibek Yeskermessuly

We investigate linear parabolic equations in divergence form with singular coefficients and nonsmooth initial--boundary data. When the diffusion, drift, or potential terms, as well…

Numerical Approaches for Identifying the Time-Dependent Potential Coefficient in the Diffusion Equation

Arshyn Altybay, Michael Ruzhansky

We address the inverse problem of identifying a time-dependent potential coefficient in a one-dimensional diffusion equation subject to Dirichlet boundary conditions and a nonlocal…

Numerical identification of the time-dependent coefficient in the heat equation with fractional Laplacian

Arshyn Altybay, Gulzat Nalzhupbayeva

We consider the inverse problem of identifying a time-dependent source coefficient in a one-dimensional heat equation governed by the spectral Dirichlet fractional Laplacian from a…

Rothe's method in direct and time-dependent inverse source problems for a semilinear pseudo-parabolic equation

Karel Van Bockstal, Khonatbek Khompysh, Arshyn Altybay

In this paper, we investigate the inverse problem of determining an unknown time-dependent source term in a semilinear pseudo-parabolic equation with variable coefficients and a Di…

Numerical Identification of a Time-Dependent Coefficient in a Time-Fractional Diffusion Equation with Integral Constraints

Arshyn Altybay

In this paper, we numerically address the inverse problem of identifying a time-dependent coefficient in the time-fractional diffusion equation. An a priori estimate is established…
