報告題目：Two inverse problems for fractional partial differential equations

報告摘要：In this talk, we will discuss two inverse problems for fractional partial differential equations. One is to identify a coefficient by final observation data. The other is an inverse source problem by boundary observation, where the source is assumed to be driven by a Gaussian random field. For both direct problems, well-posedness is shown and numerical schemes are proposed. Moreover, the inverse coefficient problem can be transferred to be an inverse source problem by linearization. And the inverse random source problem can be solved by PhaseLift. Numerical examples are presented to illustrate the effectiveness and efficiency of proposed numerical methods.
