Centerpoint Theorems for Wedges
The Centerpoint Theorem states that, for any set S of n points in R, there exists a point p in R such that every closed halfspace containing p contains at least dn/(d+ 1)e points of S. We consider generalizations of the Centerpoint Theorem in which halfspaces are replaced with wedges (cones) of angle α. In R, we give bounds that are tight for all values of α and give an O(n) time algorithm to f...
متن کاملFloodlight illumination of infinite wedges
The floodlight illumination problem asks whether there exists a one-to-one placement of n floodlights illuminating infinite wedges of angles α1, . . . , αn at n sites p1, . . . , pn in a plane such that a given infinite wedge W of angle θ located at point q is completely illuminated by the floodlights. We prove that this problem is NP-hard, closing an open problem from 2001 [6]. In fact, we sho...
متن کاملCollision of Two Liquid Wedges
1. INTRODUCTION Splashing following the collisions of liquids or granular materials is often observed in a variety of natural and engineering problems, such as plunging or breaking water waves, liquid droplets impacting on a free surface or a thin film of the same liquid, etc. Splashing leads to fluid fragmentation and the generation of drops and spray as well as fluid aeration. These phenomena...
متن کاملTransience of percolation clusters on wedges
We study random walks on supercritical percolation clusters on wedges in Z, and show that the infinite percolation cluster is (a.s.) transient whenever the wedge is transient. This solves a question raised by O. Häggström and E. Mossel. We also show that for convex gauge functions satisfying a mild regularity condition, the existence of a finite energy flow on Z is equivalent to the (a.s.) exis...
متن کاملWedges, and Capital Formation
This paper focuses on how inflation interacts with taxes and interest rates to affect capital formation.1 It uses a simple credit-market framework to explain how inflation magnifies the distorting effects of taxation when the tax treatment of interest income and expense is not fully indexed to inflation.2 The distortion involves a real tax wedge consisting of the difference between the real int...
