Remarks on quantum ???eld theory on de Sitter and anti-de Sitter space-times

摘要

This is a short review of work done in common with Jacques Bros, Michel Gaudin, Ugo Moschella, and Vincent Pasquier. Among results are explicit K?¤ll??na€“Lehmann representations for products of two free-???eld two-point functions in the de Sitter and the anti-de Sitter spaces and applications to particle decay.
