Twisted separability for adjoint functors

open access: green, 2023
Twisted separable functors generalize the separable functors of Nastasescu, Van den Bergh and Van Oystaeyen, and provide a convenient tool to compare various projective dimensions. We discuss when an adjoint functor is twisted separable, obtaining a version of Rafael's Theorem in the twisted case.

Cubical Sets and Trace Monoid Actions [PDF]

open access: yesThe Scientific World Journal, 2013
This paper is devoted to connections between trace monoids and cubical sets. We prove that the category of trace monoids is isomorphic to the category of generalized tori and it is a reflective subcategory of the category of cubical sets.

An Interpolation Theorem for Adjoint Functors [PDF]

open access: bronzeProceedings of the American Mathematical Society, 1970
0. Introduction. In this paper we present a category theoretic generalization of the construction of the tensor algebra or symmetric algebra of a module which proceeds by representing the module as the quotient of the free module on the underlying set of the given module by its module of relations, then obtaining the tensor algebra as the quotient of ...

The right adjoint to the equivariant operadic forgetful functor on incomplete Tambara functors

open access: greenHomotopy Theory: Tools and Applications, 2017
For $N_\infty$ operads $\mathcal O$ and $\mathcal O'$ such that there is an inclusion of the associated indexing systems, there is a forgetful functor from incomplete Tambara functors over $\mathcal O'$ to incomplete Tambara functors over $\mathcal O ...

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 ...
