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 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...
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 کاملMicro Frictions and Macro Wedges
Business Cycle Accounting (BCA) is a helpful litmus test for quantitive macroeconomic models. Indeed, deviations from the data and a neo-classical growth model can be summarized as distortion of the efficiency of production or to optimality conditions such as leisure-consumption choices and investment Euler equations. These empirical ”wedges” are then a simple diagnostic test for the empirical ...
