Abstract
We consider complex scalar fields in two-dimensional de Sitter space minimally coupled to an SO(2,1)-invariant Maxwell potential and construct an ultraviolet-finite functional representation of the symmetry generators in the Schrödinger picture. We find that there is a unique vacuum state which is strictly SO(2,1) invariant.This publication has 6 references indexed in Scilit:
