Abstract: Aichholzer et al. [O. Aichholzer, C. Huemer, S. Kappes, B. Speckmann, C.D. Tóth, Decompositions, partitions, and coverings with convex polygons and pseudo-triangles, Graphs and Combinatorics 23 (2007) 481–507] introduced the notion of pseudo-convex partitioning of planar point sets and proved that the pseudo-convex partition number satisfies . In this paper we prove that , which improves the upper bound on to , thus answering a question posed by Aichholzer et al. in the same paper. [Copyright &y& Elsevier]
