Abstract. We give new positive results on the long-standing open problem of geometric covering decomposition for homothetic polygons. In particu-lar, we prove that for any positive integer k, every finite set of points in R3 can be colored with k colors so that every translate of the negative octant containing at least k6 points contains at least one of each color. The best pre-viously known bound was doubly exponential in k. This yields, among other corollaries, the first polynomial bound for the decomposability of multiple coverings by homothetic triangles. We also investigate related decomposition problems involving intervals appearing on a line. We prove that no algorithm can dynamically maintain a decomposition of a multiple covering b...
