| Abstract: | LetA be a positive selfadjoint operator and letB be a symmetric perturbation ofA. We establish sufficient conditions for the essential selfadjointness ofA+B on domains whereA is essentially selfadjoint. The results have application to the   4 field theory in two space-time dimensions.Supported in part by the U.S. Air Force under Grant AFOSR 68-1453 MOD C. |
