Abstract

The Brezzi–Douglas–Marini interpolation error on anisotropic elements has been analyzed in two recent publications, the first focusing on simplices with estimates in L 2 , the other considering parallelotopes with estimates in terms of L p -norms. This contribution provides generalized estimates for anisotropic simplices for the L p case, 1≤p≤∞, and shows new estimates for anisotropic prisms with triangular base.

各向异性简单体和棱镜上的Brezzi-Douglas-Marini插值
最近的两篇论文分析了各向异性元素上的Brezzi-Douglas-Marini插值误差,第一篇论文关注的是具有l2估计的简单体,另一篇论文考虑了具有L p -范数估计的平行四边形。这一贡献提供了L p(1≤p≤∞)情况下各向异性简单体的广义估计,并给出了三角形基底的各向异性棱镜的新估计。
