AI总结:

本文针对二维和三维椭圆界面问题,建立了Crouzeix-Raviart非协调、Raviart-Thomas混合及间断伽辽金有限元方法的先验误差估计,具有对扩散系数的鲁棒性和局部解正则性的最优性。

摘要:

本文针对二维和三维椭圆界面问题,建立了Crouzeix-Raviart非协调、Raviart-Thomas混合及间断伽辽金有限元方法的先验误差估计。这些估计对扩散系数具有鲁棒性,并且在不假设扩散系数分布的情况下,对解的局部正则性具有最优性。

英文摘要:

For elliptic interface problems in two- and three-dimensions, this paper establishes a priori error estimates for Crouzeix-Raviart nonconforming, Raviart-Thomas mixed, and discontinuous Galerkin finite element approximations. These estimates are robust with respect to the diffusion coefficient and optimal with respect to local regularity of the solution. Moreover, we obtain these estimates with no assumption on the distribution of the diffusion coefficient.
