What is A counterexample to a theorem about the convexity of Powell-Sabin elements about?
We show that Theorem 4.1 of Carnicer and Dahmen (1992) is false. Let ~ be the triangle in R 2 with vertices Xl = (-2A, 0), x2 = (2,-2), x3 = (2, 2) for someA>0. Letfl =2A, f2=f3=2, andgl = (-1, 0), g2 = (0, -1), g3 = (0,1). Then the piecewise linear convex function F : ~2 \_\_+ ~,
