报告摘要:

In this talk, we consider bifurcation solutions of a free boundary problem modeling tumor growth with angiogenesis by Stokes equation. We first establish the existence and uniqueness of radially symmetric stationary solutions, then prove that there exist a positive integer $n^{**}$ and a sequence $(/mu//gamma)_n$ such that  a branch of symmetry-breaking stationary solutions bifurcate from the radially symmetric one for every $(/mu//gamma)_n$ (even $n/ge n^{**}$), where $/mu$ and $/gamma$ denote the proliferation rate and the cell-to-cell adhesiveness, respectively. We also give the impact of angiogenesis in tumor model.
