The classical de Finetti theorem for strongly quasi-invariant states

Year: 2026

Type: article

Abstract: As an application of a general theory of quasi-invariant states developed in Ref. [1], we prove a classical de Finetti type structure theorem for quasi-invariant states and, for this class of states, we also extend the conditional version of this theorem, first proved in Ref. [2].
