On convex spiral equicoverings of masses

Abstract

Convex spiral equicoverings were recently introduced by Espinosa-García, Martínez-Sandoval and Roldán-Pensado. They left open the question of whether every planar mass admits a convex (3k,k+1)-spiral equicovering. In this paper we give an affirmative answer to this question. To be precise, we prove the following: Given an integer k ≥ 2, for every planar mass there is a fan consisting of 3k equal-mass sectors such that the union of every k+1 consecutive sectors is convex.
