Bivariate C1 Quadratic Finite Elements and Vertex Splines
Following work of Heindl and of Powell and Sabin, each triangle of an arbitrary (regular) triangulation A of a polygonal region ii in R is subdivided into twelve triangles, using the three medians, yielding the refinement A of A , so that C quadratic finite elements can be constructed. In this paper, we derive the Bézier nets of these elements in terms of the parameters that describe function a...
متن کاملMultivariate Splines and Algebraic Geometry
Multivariate splines are effective tools in numerical analysis and approximation theory. Despite an extensive literature on the subject, there remain open questions in finding their dimension, constructing local bases, and determining their approximation power. Much of what is currently known was developed by numerical analysts, using classical methods, in particular the so-called Bernstein-Béz...
متن کاملGraphs, Syzygies, and Multivariate Splines
The module of splines on a polyhedral complex can be viewed as the syzygy module of its dual graph with edges weighted by powers of linear forms. When the assignment of linear forms to edges meets certain conditions, we can decompose the graph into disjoint cycles without changing the isomorphism class of the syzygy module. Thus we can use this decomposition to compute the homological dimension...
متن کاملMultivariate Differences, Polynomials, and Splines
A constructive approach to Kergin interpolation in IR k : multivariate B-splines and La-19 Corollary 4.19. Let S be a nite set in IR d and let H be the set of distinct elements from the directional matrix N. Then N (S) = X H () (S): That is, if f is a function deened on S, then there exists a polynomial in N agreeing with f on S if and only if there exist polynomials p in () such that P p agree...
