A more general categorical framework for congruence of applicative bisimilarity

Tom Hirschowitz, Ambroise Lafont

We prove a general congruence result for bisimilarity in higher-order languages, which generalises previous work to languages specified by a labelled transition system in which pro…

Variable binding and substitution for (nameless) dummies

André Hirschowitz, Tom Hirschowitz, Ambroise Lafont +1

By abstracting over well-known properties of De Bruijn's representation with nameless dummies, we design a new theory of syntax with variable binding and capture-avoiding substitut…

A unified treatment of structural definitions on syntax for capture-avoiding substitution, context application, named substitution, partial differentiation, and so on

Tom Hirschowitz, Ambroise Lafont

We introduce a category-theoreticabstraction of a syntax with auxiliary functions, called an admissiblemonad morphism. Relying on an abstract form of structural recursion,we then d…

A categorical framework for congruence of applicative bisimilarity in higher-order languages

Tom Hirschowitz, Ambroise Lafont

Applicative bisimilarity is a coinductive characterisation of observational equivalence in call-by-name lambda-calculus, introduced by Abramsky (1990). Howe (1996) gave a direct pr…

Modules over monads and operational semantics (expanded version)

André Hirschowitz, Tom Hirschowitz, Ambroise Lafont

This paper is a contribution to the search for efficient and high-level mathematical tools to specify and reason about (abstract) programming languages or calculi. Generalising the…

Cellular Monads from Positive GSOS Specifications

Tom Hirschowitz

We give a leisurely introduction to our abstract framework for operational semantics based on cellular monads on transition categories. Furthermore, we relate it for the first time…
