Title: Classical squaring relations between gauge theory and gravity

Abstract: Scattering amplitudes in gauge theory and gravity are related by a class of ``squaring’’ relations to all orders in the classical theory. This suggests that there is a link between classical solutions of these theories. In this talk, I will discuss the nature of these squaring relations, and describe a set of relations between simple solutions of Einstein gravity and gauge theory (including the cases of the Schwarzschild and Kerr black holes.) I will also show how a simple amplitude squaring relation follows from the relations between particular classical solutions.
