Dr. Lon Rosen

Lon Rosen is known internationally for his studies in constructive quantumfield theory. His first work extended the pioneering treatment by Glimm and Jaffe on the [lambda phi 4 2] model (quartically self-coupled scalar field in two-dimensional space-time) to the [P phi 2] model for which the interaction is an arbitrary polynomial bounded below. Then his name became a household word among those interested in foundations of quantum field theory when the team of Guerra, Rosen and Simon wrote their famous series of papers on Euclidean quantum field theory as classical statistical mechanics. His most recent work concerns the Yukawa Interaction of a Fermi field and a Boson field.
