Numerical Analysis of Space-Time Dependent Source Identification in Subdiffusion Equations

Siyu Cen, Bangti Jin, Yavar Kian +1

In this work, we propose an easy-to-implement fixed-point algorithm for reconstructing a space-time dependent source in a subdiffusion model from lateral boundary measurements. The…

Identification of a Point Source in the Heat Equation from Sparse Boundary Measurements

Fangyu Gong, Bangti Jin, Yavar Kian +1

In this work we investigate the inverse problem of recovering one point source in the heat equation from sparse boundary measurement, i.e., the flux data at several points on the b…

Simultaneous Identification of Coefficients and Source in a Subdiffusion Equation from One Passive Measurement

Maolin Deng, Ali Feizmohammadi, Bangti Jin +1

This article is devoted to the detection of parameters in anomalous diffusion from a single passive measurement. More precisely, we consider the simultaneous identification of coef…
