Description

In this talk I discuss some recent developments in the study of quantum fields on dS spacetimes and it’s relationship to the representation theory of SO(1, d+1). We will discuss subtleties in the treatment of gauge fields, possible resolutions and how a proper treatment of the euclidean sphere gives hints of new features that have yet to be properly understood. Based on work in progress with G. Silva, M. Sempe, V. Letsios and D. Anninos
