Abstract
We prove that n cops can capture (that is, some cop can get less than unit distance from) a robber in a continuous square region with side length less than 5n and hence that ⌊n/5⌋+1 cops can capture a robber in a square with side length n . We extend these results to three dimensions, proving that 0.34869…n2+O(n)0.34869…n2+O(n) cops can capture a robber in an n×n×nn×n×n cube and that a robber can forever evade fewer than 0.02168…n2+O(n)0.02168…n2+O(n) cops in that cube.
