Title:
The Einstein-Infeld-Hoffmann legacy in mathematical relativity

Speaker:
Michael Kiessling

Abstract:
Einstein’s General Relativity Theory is usually summarized, in a nutshell, as follows: “Matter tells spacetime how to curve, and spacetime curvature tells matter how to move.” In particular, one learns that uncharged point particles of rest mass m >0 move along (time-like) geodesics. This law of geodetic motion is based on the notion of “test particle” — a theoretical fiction which assumes that the contribution of the very point particle to the curvature of spacetime can be ignored. In their Annals of Mathematics paper of 1938, Albert Einstein, Leo Infeld, and Banesh Hoffmann tried to go beyond this test-particle fiction by arguing that Einstein’s gravitational field equations would also dictate the motion of point particles which “do tell spacetime how
