 abstract={The paper shows for several cases of compact, convex sets K that G (z) = 1/z² is not a 2-dimensional Haar space generator for K, implying that it is not a universal Haar space generator for K. The above G is not a 3-dimensional Haar space generator for all regular polygons with smoothed vertices. The paper contains an overview of the joint work of Walter Hengartner and the present author.},
