报告摘要：In this talk, a free boundary problem for vascularized tumor growth with a necrotic core and time delays is discussed. In the problem, there are two free boundaries, one is the outer boundary of the tumor, the other is the necrotic core boundary inside the tumor. The time delay exists in the process of tumor growth and represents the time required for tumor cell division.

Sufficient conditions for the existence, uniqueness, and stability of the stationary solution to the model are given. The results show that the time delay does not affect the final growth behavior of tumor.
