摘  要:
研究一个描述肿瘤生长的自由边界问题,它来源于Helen-Byrne描述的体外模拟单层肿瘤细胞连续性生长的数学模型.该模型主要研究肿瘤生长过程中细胞间的相互作用(张力和斥力)引起的内部变化.作者运用椭圆型偏微分方程的逼近方法、Lp理论和Schauder不动点理论证明了这个问题整体解的存在性.

摘  要:
A free boundary problem model of the growth of tumor which came from monolayer tumor cells model in vitro by Helen-Byrne was studied. With the model,internal change through cell-cell interactions was mainly studied using approximation method combined with Schauder fixed point theorem and the Lptheory,it was proved that the problem had a global solution in any given time.
