报告摘要:

In this talk we discuss some inverse problems raised from a moving boundary model of breast cancer, so-called ductal carcinoma in situ (DCIS). We introduced a number of inverse problems of moving boundary model of DCIS. Then we will present some resent results related to the inverse problems. We use some transformation and heat potential theory to establish the integral form of solution and proved the existence and uniqueness of solution to the related problems. Then we consider the inverse problem of determining the potential function of model from moving boundary information, which related to the mammography screening of DCIS. Algorithm and numerical simulation are presented to demonstrate the validity and applicability of solutions.
