Título: Beyond General Relativity: exponential gravity as a particular case
Abstract: In this talk I will review the basis of some types of modified gravities, their pros and cons, the possibility of reproducing late-time acceleration and their viability. A particular case will be analysed, based on exponential terms in the gravitational action. This type of models may be capable of reproducing both inflation as the late-time acceleration. I will discuss the constraints coming from different sources of data, both at the inflationary epoch as at late times by using Sne Ia, BAO and Hubble data. As will be shown, exponential gravity may be kept as a promising candidate for dark energy and inflation.
