Chromatic Number of the Plane & Its Relatives, History, Problems and Results: An Essay in 11 Parts

  • Alexander Soifer
Chapter
Part of the Progress in Mathematics book series (PM, volume 285)

Abstract

In August 1987 I attended an inspiring talk by Paul Halmos at Chapman College in Orange, California. It was entitled “Some Problems You Can Solve, and Some You Cannot.” This problem was an example of a problem “you cannot solve.”
