Abstract

Pach and Tóth [14] proved that any n-vertex graph of genus g and maximum degree d has a planar crossing number at most cgdn, for a constant c 1. We improve on this results by decreasing the bound to O(dgn), if g = o(n), and to O(g2), otherwise, and also prove that our result is tight within a constant factor.
