离散de Rham复形的局部有界交换投影算子

Local Bounded Commuting Projection Operator for Discrete de Rham Complexes

Jun Hu, Yizhou Liang, Ting Lin

摘要:

系统地构造了二维和三维非标准有限元de Rham复形的局部有界交换投影算子。主要结果的假设是温和的,可以验证。对于三维问题,其结果可应用于标准的有限元de Rham复形、Hermite复形、Argyris复形和Neilan的Stokes复形。对于二维情形,该结果可应用于Hermite-Stenberg复形和Falk-Neilan Stokes复形。

英文摘要:

The local bounded commuting projection operators of nonstandard finite element de Rham complexes in two and three dimensions are constructed systematically. The assumptions of the main result are mild and can be verified. For three dimensions, the result can be applied to the standard finite element de Rham complex, Hermite complex, Argyris complex and Neilan's Stokes complex. For two dimensions, the result can be applied to the Hermite--Stenberg complex and the Falk--Neilan Stokes complex.
