Verdier duality on conically smooth stratified spaces

open access: yes, 2023
In this paper we prove a duality for constructible sheaves on conically smooth stratified spaces. Here we consider sheaves with values in a stable and bicomplete $\infty$-category equipped with a closed symmetric monoidal structure, and in this setting ...

Coherence Completions of Categories and Their Enriched Softness

open access: yes, 1997
We summarize some recent results on coherence completions of categories. Our goal is to demonstrate that there is a close connection between Girard's coherence spaces and free bicomplete categories. We extend coherence spaces to C-valued coherence spaces

Bicompleteness of the fine quasi-uniformity

open access: yes, 2017
A characterization of the topological spaces that possess a bicomplete fine quasi-uniformity is obtained. In particular we show that the fine quasi-uniformity of each sober space, of each first-countable T1-space and of each quasi-pseudo-metrizable space

Almost 2-Fully Normal, Pairwise Paracompact and Complete Developable Bispaces

open access: yes, 2004
We introduce and study the notion of an almost 2-fully normal bispace. In particular; we prove that a bispace is quasi-pseudometrizable if and only if it is almost 2-fully normal and pairwise developable.

Abstract From Parity Games to Circular Proofs

open access: yes, 2008
We survey on the ongoing research that relates the combinatorics of parity games to the algebra of categories with finite products, finite coproducts, initial algebras and final coalgebras of definable functors, i.e. µ-bicomplete categories.

Cuts for circular proofs

open access: yes
One of the authors introduced in [1] a calculus ofcircular proofs for studying the computability arising from thefollowing categorical operations: finite products and coproducts,initial algebras, final coalgebras.

The six operations in topology

open access: yes, 2023
In this paper we show that the six functor formalism for sheaves on locally compact Hausdorff topological spaces, as developed for example in Kashiwara and Schapira's book Sheaves on Manifolds, can be extended to sheaves with values in any closed ...
