Abstract EN
In this paper, we consider a time-delayed free boundary problem with time dependent Robin boundary conditions.
The special case where n=3 is a mathematical model for the growth of a solid nonnecrotic tumor with angiogenesis.
In the problem, both the angiogenesis and the time delay are taken into consideration.
Tumor cell division takes a certain length of time, thus we assume that the proliferation process leg behind as compared to the process of apoptosis.
The angiogenesis is reflected as the time dependent Robin boundary condition in the model.
Global existence and uniqueness of the nonnegative solution of the problem is proved.
When c>0 is sufficiently small, the stability of the steady state solution is studied, where c is the ratio of the time scale of diffusion to the tumor doubling time scale.
Under some conditions, the results show that the magnitude of the delay does not affect the final dynamic behavior of the solutions.
An application of our results to a mathematical model for tumor growth of angiogenesis is given and some numerical simulations are also given.
