Towards a CPT Invariant Quantum Field Theory on Elliptic de Sitter Space

Abstract

Consequences of Schrödinger's antipodal identification on quantum field theory in de Sitter space are investigated. The elliptic ${\mathbb{Z}}_2$ identification provides observers with complete information. We show that a suitable confinement on dimension of the elliptic de Sitter space guarantees the existence of globally defined spinors and orientable $dS/{\mathbb{Z}}_2$ manifold. In Beltrami coordinates, we give exact solutions of scalar and spinor fields. The CPT invariance of quantum field theory on the elliptic de Sitter space is presented explicitly.
