Planar diagrammatics of self-adjoint functors and recognizable tree series [PDF]

open access: yesPure and Applied Mathematics Quarterly, 2021
A pair of biadjoint functors between two categories produces a collection of elements in the centers of these categories, one for each isotopy class of nested circles in the plane.

A characterization of finite \'etale morphisms in tensor triangular geometry [PDF]

open access: yesÉpijournal de Géométrie Algébrique, 2022
We provide a characterization of finite \'etale morphisms in tensor triangular geometry. They are precisely those functors which have a conservative right adjoint, satisfy Grothendieck--Neeman duality, and for which the relative dualizing object is ...

Green correspondence and relative projectivity for pairs of adjoint functors between triangulated categories [PDF]

open access: yes, 2020
Auslander and Kleiner proved in 1994 an abstract version of Green correspondence for pairs of adjoint functors between three categories. They produce additive quotients of certain subcategories giving the classical Green correspondence in the special ...

Cotorsion pairs and adjoint functors in the homotopy category of N-complexes [PDF]

open access: yesJournal of Algebra and its Applications, 2019
In this paper, we first construct some complete cotorsion pairs on the category [Formula: see text] of unbounded [Formula: see text]-complexes of Grothendieck category [Formula: see text], from two given cotorsion pairs in [Formula: see text].

Ticking clocks as dependent right adjoints: Denotational semantics for clocked type theory [PDF]

open access: yesLogical Methods in Computer Science, 2020
Clocked Type Theory (CloTT) is a type theory for guarded recursion useful for programming with coinductive types, allowing productivity to be encoded in types, and for reasoning about advanced programming language features using an abstract form of step ...

On the Lambek Calculus with an Exchange Modality [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2019
In this paper we introduce Commutative/Non-Commutative Logic (CNC logic) and two categorical models for CNC logic. This work abstracts Benton's Linear/Non-Linear Logic by removing the existence of the exchange structural rule.

ADJOINT FUNCTORS BETWEEN CATEGORIES OF HILBERT $C^{\ast }$ -MODULES [PDF]

open access: yesJournal of the Institute of Mathematics of Jussieu, 2014
Let $E$ be a (right) Hilbert module over a $C^{\ast }$ -algebra $A$ . If $E$ is equipped with a left action of a second $C^{\ast }$ -algebra $B$ , then tensor product with $E$ gives rise to a functor from the category of Hilbert $B$ -modules to the ...
