Approximation power of polynomial splines on T-meshes
Polynomial spline spaces defined on T-meshes are useful tools for both surface modeling and the finite element method. Here the approximation power of such spline spaces is established. The approach uses Bernstein-Bezier methods to get precise conditions on the geometry of the meshes which lead to local and stable bases. (c) 2012 Elsevier B.V. All rights reserved.
