A Primer on Unimodular Gravity (2301.07641v6)
Published 18 Jan 2023 in gr-qc and hep-th
Abstract: This chapter provides an introduction to Unimodular Gravity both at the classical and quantum level, discussing the r^ole it might play in the partial solution of the Cosmological Constant problem. The main objective of this work is to serve as a conceptual introduction to Unimodular gravity without disregarding computational detail. In that sense, techniques used at the research level are presented and applied in detail.
