Zero modes in de Sitter background
Abstract There are five well-known zero modes among the fluctuations of the metric of de Sitter (dS) spacetime. For Euclidean signature, they can be associated with certain spherical harmonics on the S 4 sphere, viz., the vector representation 5 of the global SO(5) isometry. They appear, for example...
