Union of Reducibility Candidates for Orthogonal Constructor Rewriting
We revisit Girard's reducibility candidates by proposing a general of the notion of neutral terms. They are the terms which do not interact with some contexts called eliminati...

On the Values of Reducibility Candidates
The straightforward elimination of union types is known to break subject reduction, and for some extensions of the lambda-calculus, to break strong normalization as well. Similarly...

Supervision of integral-input-to-state stabilizing controllers
The subject of this paper is hybrid control of nonlinear systems with large-scale uncertainty. We describe a high-level controller, called a "supervisor", which orchestr...

Strong Normalization as Safe Interaction
When enriching the λ-calculus with rewriting, union types may be needed to type all strongly normalizing terms. However, with rewriting, the elimination rule (∨ E) of union typ...
