Everything You Always Wanted To Know About The Cosmological Constant Problem

Publisher: arXiv 2012
Number of pages: 89
This article aims at discussing the cosmological constant problem at a pedagogical but fully technical level. We review how the vacuum energy can be regularized in flat and curved space-time and how it can be understood in terms of Feynman bubble diagrams.

Inflation is today the main theoretical framework that describes the early Universe. These lectures give an introduction to inflation and the production of primordial perturbations, and a review of some of the latest developments in this domain.

Cosmography is in fact a kinematics of cosmological expansion. The effectiveness of cosmography lies in the fact that it allows, based on the observations, to perform a rigid selection of models that do not contradict the cosmological principle.

This is a review of the physics and cosmology of the cosmological constant. The author presents an overview of cosmology in the presence of a cosmological constant, observational constraints on its magnitude, and the physics of a small vacuum energy.
