报告摘要 Abstract:

This talk is concerned with several inverse problems of multiple parameters in time-fractional diffusion-wave equation, including inverse problem of two initial values, .inverse fractional order and potential coefficient problem as well as inverse fractional order and advection coefficient problem. The uniqueness results of the mentioned inverse problems are established. Then we adopted some regularization methods for reconstructing the unknown parameters, and numerical results are presented to show the efficiency of our methods.
