Abstract

We introduce a new class of fat, not necessarily convex or polygonal, objects in the plane, namely locally γ-fat objects. We prove that the union complexity of any set of n such objects is O(λ s+2(n)log 2 n). This improves the best known bound, and extends it to a more general class of objects.
