Abstract

The main point of the present work is the realisation of in ationary periods based on vector fields. The knowledge needed to achieve this objective were introduced in a systematic manner, in the order that the author found more logical. In the first chapter numerous details about our universe and the present capacity to observe it were described. In the second, the standard model of cosmology is presented. Some of the most important results of General Relativity and observational cosmology are also presented, and on these grounds the theoretical fundaments of Cosmology are estabilished. In the third chapter in ationary cosmology is studied, and its most important results and some well known models based on scalar fields are presented. In the fourth chapter begins the study of in ationary periods that uses vector fields. This subject attracted attention and generated many papers in the year of 2008. At last, the author¿s impressions and future perspectives in the subject are presented (AU)
