On Progress for Structured Communications [PDF]

, 2008
We propose a new typing system for the π-calculus with sessions, which ensures the progress property, i.e. once a session has been initiated, typable processes will never starve at session channels. In the current literature progress for session types has been guaranteed only in the case of nested sessions, disallowing more than two session channels ...
