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…

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…

Simple game semantics and Day convolution

Clovis Eberhart, Tom Hirschowitz, Alexis Laouar

Game semantics has provided adequate models for a variety of programming languages, in which types are interpreted as two-player games and programs as strategies. Melliès (2018) su…
