【摘要】 研究了一类间断系数变分不等式解的奇性,得到了解的先验估计。在解的奇点附近构造了一类有限元网格剖分,根据这种剖分,有限元解具有通常情形(即没有奇性时)的收敛速度。更多还原

【Abstract】 The singularity of the solution of variational inequalities with coefficients that are dis-continuous across the interface is investigated,a prior estimate is obtained.We also design a netshape of the finite elements around the singular points of the solution.By means of this net,weprove that the approximate solution has the same convergence rate as that without singularity.更多还原
