Multiparty session types (MSTs) are a type-based approach to verifying communication
protocols. Central to MSTs is a projection operator: a partial function that maps protocols …

Session types provide a ty** discipline for structured communication on bidirectional
channels. Context-free session types overcome the restriction to tail recursive protocols …

Multiparty session types (MSTs) provide efficient means to specify and verify asynchronous
message-passing systems. For a global type, which specifies all interactions between roles …

We study increasingly expressive type systems, from Fµ—an extension of the polymorphic
lambda calculus with equirecursive types—to Fµ; ω—the higher-order polymorphic lambda …

Session types statically prescribe bidirectional communication protocols for message-
passing processes. However, simple session types cannot specify properties beyond the …

In sequential languages, dynamic contracts are usually expressed as boolean functions
without externally observable effects, written within the language. We propose an analogous …

Session types have emerged as a powerful paradigm for structuring communication-based
programs. They guarantee type soundness and session fidelity for concurrent programs with …

Session types statically describe communication protocols between concurrent message-
passing processes. Unfortunately, parametric polymorphism even in its restricted prenex …

We present an algorithm to decide the equivalence of context-free session types, practical to
the point of being incorporated in a compiler. We prove its soundness and completeness …

We propose session-ocaml, a novel library for session-typed concurrent/distributed
programming in OCaml. Our technique solely relies on parametric polymorphism, which can …
