The Yao Graph Y_6 is a Spanner

Abstract

We prove that Y_6 is a spanner. Y_6 is the Yao graph on a set of planar points, which has an edge from each point x to a closest point y within each of the six angular cones of 60 deg surrounding x.

12 pages, 11 figures, 2 references, unpublished. A subcase of Case(2) of Theorem 1 was overlooked, and I withdraw the paper until that gap is filled.
