s – Lectures Thursday, December 1, 9:00-10:30 Lecture 1: Spline approximation Stefan Takacs RICAM, Computational Methods for PDEs Thomas Takacs JKU Linz, Institute of Applied Geometry In the first part of the lecture we discuss standard approximation properties for B-spline and NURBS spaces. B-splines are piecewise polynomial functions of a given prescribed smoothness. NURBS stands for non-unif...
