Report summary:

Subdiffusion arises in many physical and engineering applications, and is often modeled by a parabolic type equation with a Caputo fractional derivative in time. In this talk, we discuss a nonlinear inverse problem of recovering the potential term from the final time measurement. We discuss the local stability property via linearization and numerical reconstruction via fixed point algorithm.

Brief introduction of the speaker:

Prof. Bangti Jin received Ph.D. degree in applied mathematics from the Chinese University of Hong Kong, Hong Kong, in 2008.
