摘要
研究了乳腺癌的早期生长模型(DCIS),它为耦合了抛物方程、椭圆方程的自由边界问题.运用椭圆型方程的变分理论、抛物方程的Lp理论和压缩映照原理,证明了这个问题局部解的存在惟一性,然后用延拓方法得到了整体解的存在惟一性.
The paper studies a problem of modelling the early growth of ductal carinoma in situ of the breast (DCIS). This model has decoupled parabolic equations and hyperbolic equations. The variational theory of hyperbolic equations, L^p-theory of parabolic equations and Banach fixed point theorem are used to prove the existence and uniqueness of a local solution, and the continuation method is applied to get the existence and uniqueness of a global solution.
