Our development is carried out in a minimal setting considering classic (binary) sessions, but building on and generalising previous work on progress analysis in the context of conversation types. Our contributions aim at underpinning forthcoming works on progress for session-typed systems, so as to support richer verification procedures based on a more foundational approach. Although this work does not target expressiveness, our approach already addresses challenging scenarios which are unaccounted for elsewhere in the literature, in particular systems that interleave communications on received session channels. %I Springer %D 2013 %A Hugo Torres Vieira %A Vasco Thudichum Vasconcelos %N 7890 %B Coordination Models and Languages %O Proceedings of the 15th International Conference, COORDINATION 2013, Held as Part of the 8th International Federated Conference on Distributed Computing Techniques, DisCoTec 2013, Florence, Italy, June 3-5, 2013.
