关于S_5~2(Δ_(mn)^(2))插值与逼近

主要讨论了矩形区域在II—型三角剖分下,一类具有C2连续的二元五次多项式插值逼近问题,并证明了它的存在性、唯一性,给出了它的逼近度。

Double Periodic Cubic Spline Spaces over Non-Uniform Type-2 Triangulations

In this paper, the dimension of the double periodic cubic C^1 spline space over non-uniform type-2 triangulations is determined and a local support basis is given.
