A Construction of Cr Conforming Finite Element Spaces in Any Dimension
Abstract
This paper proposes a construction of Cr conforming finite element spaces with arbitrary r in any dimension. It is shown that if k 2dr+1 the space Pk of polynomials of degree k can be taken as the shape function space of Cr finite element spaces in d dimensions. This is the first work on constructing such Cr conforming finite elements in any dimension in a unified way. It solves a long-standing open problem in finite element methods.
