带收缩小洞区域上Laplace方程的一致估计(二)
报告摘要
:
In this talk, we consider the Dirichlet problem of the Laplace equation in a domain with a shrinking hole in . A typical observation is that, the Lipschitz norm of the domain goes to infinity as the size of the hole goes to zero. Thus, if , the classical results indicate that the estimate of the solution may go to infinity as the size of the hole tends to zero. We give a complete description for the uniformestimates of the solution for all : we show that the uniformestimate holds if and only if( when ).
