摘要
考察了二维稳态Stokes问题的基于速度──压力形式的非协调C－R有限元逼近．利用Sobolev权模技巧和权模LBB条件，得到了稳态Stokes问题速度和压力逼近解的拟最优的最大模估计．
The paper deals with the nonconforming C-R approximate schemes for velocity-pressure mixed formulations of the stationary stokes problerns in 2 - D. The quasi- optitnal maximum norm error estimates of approximate soutions of the stationary stokes problems are obtained for the velocity, its gradient and the pressure fields,by means of chlev weighted norm methed and weighted LBB condition.
