报告摘要: This is a joint work with Prof. Durvudkhan Suragan. In this talk, we discuss inverse problems related to determining the time-dependent coefficient and unknown source function of fractional heat equations. Our approach shows that having just one set of data at an observation point ensures the existence of a weak solution for the inverse problem. Furthermore, if there is an additional datum at the observation point, it leads to a specific formula for the time-dependent source coefficient. Moreover, we investigate inverse problems involving non-local data and recovering the space-dependent source function of the fractional heat equation. We also discuss extensions of these results to time and space fractional heat equations. The talk is based on our recent results from [1]-[3].
