Bisimulations for Delimited-Control Operators

Dariusz Biernacki ; Sergueï Lenglet ; Piotr Polesiuk.

We present a comprehensive study of the behavioral theory of an untyped $\lambda$-calculus extended with the delimited-control operators shift and reset. To that end, we define a contextual equivalence for this calculus, that we then aim to characterize with coinductively defined relations, called&nbsp;[&hellip;]

Environmental Bisimulations for Delimited-Control Operators with Dynamic Prompt Generation

Andrés Aristizábal ; Dariusz Biernacki ; Sergueï Lenglet ; Piotr Polesiuk.

We present sound and complete environmental bisimilarities for a variant of Dybvig et al.'s calculus of multi-prompted delimited-control operators with dynamic prompt generation. The reasoning principles that we obtain generalize and advance the existing techniques for establishing program&nbsp;[&hellip;]

Faithful (meta-)encodings of programmable strategies into term rewriting systems

Horatiu Cirstea ; Serguei Lenglet ; Pierre-Etienne Moreau.

Rewriting is a formalism widely used in computer science and mathematical logic. When using rewriting as a programming or modeling paradigm, the rewrite rules describe the transformations one wants to operate and rewriting strategies are used to con- trol their application. The operational semantics&nbsp;[&hellip;]

Proving Soundness of Extensional Normal-Form Bisimilarities

Dariusz Biernacki ; Serguei Lenglet ; Piotr Polesiuk.

Normal-form bisimilarity is a simple, easy-to-use behavioral equivalence that relates terms in $\lambda$-calculi by decomposing their normal forms into bisimilar subterms. Moreover, it typically allows for powerful up-to techniques, such as bisimulation up to context, which simplify bisimulation&nbsp;[&hellip;]

Fully Abstract Encodings of $\lambda$-Calculus in HOcore through Abstract Machines

Małgorzata Biernacka ; Dariusz Biernacki ; Sergueï Lenglet ; Piotr Polesiuk ; Damien Pous ; Alan Schmitt.

We present fully abstract encodings of the call-by-name and call-by-value $\lambda$-calculus into HOcore, a minimal higher-order process calculus with no name restriction. We consider several equivalences on the $\lambda$-calculus side -- normal-form bisimilarity, applicative bisimilarity, and&nbsp;[&hellip;]
