We then consider disjointness in this context, in particular for ergodic versus identity systems. Lastly we show how multitime correlation functions appearing in quantum statistical mechanics naturally fit into this joining framework.enElsevierC-dynamical systemsJoiningsFree products (Group theory)Postprint Article
