Recursive subtyping revealed
Algorithms for checking subtyping between recursive types lie at the core of many programming language implementations. But the fundamental theory of these algorithms and how they...

A Duality in Proof Systems for Recursive Type Equality and for Bisimulation Equivalence on Cyclic Term Graphs
This paper is concerned with a proof-theoretic observation about two kinds of proof systems for regular cyclic objects. It is presented for the case of two formal systems that are...

Constructive Membership Predicates as Index Types
In the constructive setting, membership predicates over recursive types are inhabited by terms indexing the elements that satisfy the criteria for membership. In this paper, we mo...

An Operational Domain-theoretic Treatment of Recursive Types
We develop a domain theory for treating recursive types with respect to contextual equivalence. The principal approach taken here deviates from classical domain theory in that we ...

A Typed Lambda Calculus with Categorical Type Constructors
A typed lambda calculus with categorical type constructors is introduced. It has a uniform category theoretic mechanism to declare new types. Its type structure includes categoric...

Subtyping Recursive Types
We investigate the interactions of subtyping and recursive types, in a simply typed λ-calculus. The two fundamental questions here are whether two (recursive) types are in the su...

Efficient and Flexible Matching of Recursive Types
Equality and subtyping of recursive types have been studied in the 1990s by Amadio and Cardelli; Kozen, Palsberg, and Schwartzbach; Brandt and Henglein; and others. Potential appl...

Step-Indexed Syntactic Logical Relations for Recursive and Quantified Types
We present a sound and complete proof technique, based on syntactic logical relations, for showing contextual equivalence of expressions in a -calculus with recursive types and imp...

Type Inference for Recursive Definitions
We consider type systems that combine universal types, recursive types, and object types. We study type inference in these systems under a rank restriction, following Leivant'...
