Comparison theorems for Kan, faintly universal and strongly universal derived functors [PDF]

open access: yesSurveys in Mathematics and its Applications, 2022
We distinguish between faint, weak, strong and strict localizations of categories at morphism families and show that this framework captures the different types of derived functors that are considered in the literature.

Generalizing determinization from automata to coalgebras [PDF]

open access: yesLogical Methods in Computer Science, 2013
The powerset construction is a standard method for converting a nondeterministic automaton into a deterministic one recognizing the same language. In this paper, we lift the powerset construction from automata to the more general framework of coalgebras ...

Innocent Strategies as Presheaves and Interactive Equivalences for CCS [PDF]

open access: yesScientific Annals of Computer Science, 2012
Seeking a general framework for reasoning about and comparing programming languages, we derive a new view of Milner's CCS. We construct a category E of plays, and a subcategory V of views.

Categorial compositionality: a category theory explanation for the systematicity of human cognition. [PDF]

open access: yesPLoS Computational Biology, 2010
Classical and Connectionist theories of cognitive architecture seek to explain systematicity (i.e., the property of human cognition whereby cognitive capacity comes in groups of related behaviours) as a consequence of syntactically and functionally ...

Gorenstein derived functors [PDF]

open access: yesProceedings of the American Mathematical Society, 2004
Over any associative ring R R it is standard to derive H o m R ( − , − ) \mathrm {Hom}_R(-,-) using projective resolutions in the first variable, or injective resolutions in the second variable, and doing this ...

Faithful actions from hyperplane arrangements [PDF]

open access: yes, 2018
We show that if X is a smooth quasiprojective 3–fold admitting a flopping contraction, then the fundamental group of an associated simplicial hyperplane arrangement acts faithfully on the derived category of X.

On the Casselman-Jacquet functor [PDF]

open access: yes, 2019
We study the Casselman-Jacquet functor $J$, viewed as a functor from the (derived) category of $(\mathfrak{g},K)$-modules to the (derived) category of $(\mathfrak{g},N^-)$-modules, $N^-$ is the negative maximal unipotent.

Homotopy theory of Moore flows (II)

open access: yesExtracta Mathematicae, 2021
This paper proves that the q-model structures of Moore flows and of multipointed d-spaces are Quillen equivalent. The main step is the proof that the counit and unit maps of the Quillen adjunction are isomorphisms on the q-cofibrant objects (all objects ...

Moduli spaces of torsion sheaves on K3 surfaces and derived equivalences [PDF]

open access: yes, 2016
We show that for many moduli spaces M of torsion sheaves on K3 surfaces S, the functor D(S) -> D(M) induced by the universal sheaf is a P-functor, hence can be used to construct an autoequivalence of D(M), and that this autoequivalence can be factored ...

The hitchhiker guide to Categorical Banach space theory. Part II.

open access: yesExtracta Mathematicae, 2021
What has category theory to offer to Banach spacers? In this second part survey-like paper we will focus on very much needed advanced categorical and homological elements, such as Kan extensions, derived category and derived functor or Abelian hearts of ...
