Inverse Source Problem for a Time-Fractional Diffusion-Wave Equation with a Singular Inverse-Square Potential

Zewen Wang, Bin Wu, Yikan Liu +2

This paper investigates an inverse source problem for a time-fractional diffusion-wave equation with a singular inverse-square potential. The source term is assumed to consist of a…

Identifying the source term in a viscoelastic membrane with a Riemann-Liouville time derivative by the partial interior observation

Zhiwei Yang, Yikan Liu

This paper studies an inverse source problem for a viscoelastic membrane, where the material's memory effect is characterized by the Riemann-Liouville fractional derivative. The pr…

Numerical reconstructions of a source term in a mobile-immobile diffusion model from the partial interior observation

Zhiwei Yang, Yikan Liu

We consider an inverse source problem in the two-time-scale mobile-immobile fractional diffusion model from partial interior observation. Theoretically, we combine the fractional D…
