del Campo, SHerrera, R2024-07-032024-07-032005-07-07CLASSICAL AND QUANTUM GRAVITY, Volume 22, Issue 13, Page 2687-26990264-9381https://repositorio.unab.cl/handle/ria/58185INDEXACIÓN: WEB OF SCIENCE.In this paper, we study a type of model for a closed inflationary universe using the Jordan-Brans-Dicke theory. Herein we determine and characterize the existence of Omega > 1, together with the period of inflation. We have found that our model, which takes into account a Jordan-Brans-Dicke type of theory, is less restrictive than that used in Einstein's theory of general relativity. Our results are compared to those found in Einstein's theory of relativity.enNATURAL INFLATIONCONSTRAINTSCREATIONBUBBLEMODELSExtended closed inflationary universesArtículoCC BY 3.0 ATRIBUCIÓN 3.0 NO PORTADA Deed10.1088/0264-9381/22/13/012
