报告摘要:

The inverse problems for fractional diffusion equation have aroused many researchers’ interest over the last few years, but quite a few work are carried out from the Bayesian point of view. In this talk, we will consider a nonlinear inverse problem for time-space fractional diffusion equation, specifically, we are interested in simultaneously identification of the source function and the orders of both time and space fractional derivative. The inverse problem will be formulated in the Bayesian framework, the well-definedness and well-posedness of the corresponding Bayesian inverse problem will be involved, the numerical implementation for 1-D case will be carried out via the iterative regularizing Kalman method and the relevant numerical results will be presented as well.
