It is demonstrated that preheating in both these cases closely resembles that in Minkowski spacetime. Furthermore, quantitative differences between preheating in spatially-flat and open models of inflation remain of order $10^{-2}$ for the chaotic inflation initial conditions considered here.", "revisions": [ { "version": "v2", "updated": "1997-04-21T02:34:50.000Z" } ], "analyses": { "subjects": [ "98.80.Cq", "04.62.+v" ], "keywords": [ "analytic results", "massless case", "expanding universe", "preheating", "open models" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Phys.
