一类加密三角剖分下的二元七次样条函数空间

The Space of Bivariate C^2 Splines of Degree Seven over a Refined Triangulation

采用B网方法,通过构造一类加密三角剖分△W下二元七次C2光滑样条函数空间S72(△W)的一个最小决定集,给出了该空间的维数.

Let S7^2 （△w） be the bivariate C^2 spline space of degree seven over a refined triangulation △w. In this paper, the dimension of S7^2 （△w） is determined by using the technique of minimal determining set.
