Richard Lavine, mathematician

Richard Lavine was a senior in mathematics at Princeton when I was visiting there as an instructor in physics. He solved some problems of analytic completion in Wightman theory by using the Ruelle coordinates, that is, the logarithms of the Lorentz invariants. The edge of the wedge theorem then gives analyticity on the join of some tubes, and Hartog's theorem on convex tubes then does the rest.

Richard went on to MIT where he worked on scattering theory.
