The results are in agreement with those obtained previously using the instanton methods. This is true even when the size of the instanton is comparable to the size of the de Sitter horizon.4 p.application/pdfeng(c) The American Physical Society, 1994CosmologyRelativitat (Física)Gravetat quànticaTeoria de camps (Física)Partícules (Física nuclear)CosmologyRelativity (Physics)Quantum gravityField theory (Physics)Particles (Nuclear physics)info:eu-repo/semantics/article507978info:eu-repo/semantics/openAccess
