Combinatorial manifolds and Kleene's theorem, homotopically
Yorgo Chamoun
We give a general method to build categories of combinatorial manifolds, i.e. categories of combinatorial objects satisfying some local property at every "point", as coreflective s…
Realization of relational presheaves
Yorgo Chamoun, Samuel Mimram
Relational presheaves generalize traditional presheaves by going to the category of sets and relations (as opposed to sets and functions) and by allowing functors which are lax. Th…
De Morgan's law in toposes I
Olivia Caramello, Yorgo Chamoun
We study toposes satisfying De Morgan's law, in particular we give characterizations of geometric theories whose classifying topos is De Morgan, clarifying the link with the amalga…
Non-Hausdorff manifolds over locally ordered spaces via sheaf theory
Yorgo Chamoun, Emmanuel Haucourt
Locally ordered spaces can be used as topological models of concurrent programs: the local order models the irreversibility of time during execution. Under certain conditions, one…
Internal parametricity, without an interval
Thorsten Altenkirch, Yorgo Chamoun, Ambrus Kaposi +1
Parametricity is a property of the syntax of type theory implying, e.g., that there is only one function having the type of the polymorphic identity function. Parametricity is usua…
