FINITE ELEMENT APPROXIMATION WITH THE VARIABLE MESH FOR A PARABOLIC VARIATIONAL INEQUALITY
抛物型变分不等式的变网格有限元方法

Finite element approximation for a variational inequality of parabolic type, for which themesh in space may be changed with time step, is considered. Under realistic regularity assum-ptions on the exact solution, an error estimate in a certain norm is proved.
