Variations on quantum de Finetti theorems and operator valued Martin boundaries: a Choquet-Deny approach
Benoît Collins, Thierry Giordano, Ryosuke Sato
We revisit the quantum de Finetti theorem. We state and prove a couple of variants thereof. In parallel, we introduce an operator version of the Martin boundary on quantum groups a…
