摘要
本文讨论了一类带有两个变函数的非线性变分不等式的问题,以及它们的有限元逼近。所考虑的区域ΩR^n真不必为凸区域,只需边界分片光滑即可。文中证明了有限元逼近的收敛性,并给出了逼近的误差估计,特别是最大模估计。
In this paper, we have discussed a class of nonlinear variational inequalities with two variable functions aud their approximations by finite element method. The domain considered here has piecewise smooth boundary and is not necessarily convex. The convergences have been proved and their error estimates, especially maximum norm estimates, have been given.
