Relational Algebra by Way of Adjunctions [PDF]

open access: yes, 2018
Bulk types such as sets, bags, and lists are monads, and therefore support a notation for database queries based on comprehensions. This fact is the basis of much work on database query languages.

Linear usage of state [PDF]

open access: yesLogical Methods in Computer Science, 2014
We investigate the phenomenon that "every monad is a linear state monad". We do this by studying a fully-complete state-passing translation from an impure call-by-value language to a new linear type theory: the enriched call-by-value calculus.

Homotopy theory of modules over diagrams of rings

open access: yesProceedings of the American Mathematical Society, Series B, 2014
Given a diagram of rings, one may consider the category of modules over them. We are interested in the homotopy theory of categories of this type: given a suitable diagram of model categories ℳ(𝓈) (as 𝓈 runs through the diagram ...

Estimation of influence of heat-conducting inclusions on thermal protection of filler constructions of buildings [PDF]

open access: yesE3S Web of Conferences, 2019
Article represents recommendations on decrease in heat losses through heat-conducting inclusions of filler constructions of buildings. Recommendations are based on the analysis of calculations by a finite element method in software package Elcut.

Topological Relations.

open access: yesRevista Integración, 2021
A family of constructs is proposed that generalizes the notion of closure operator associated to a partial order. The constructs of the family (and some of its sub constructs) hold adjoint relations with Gconv which ensure a topological resemblance ...

Cyclic multicategories, multivariable adjunctions and mates [PDF]

open access: yes, 2014
A multivariable adjunction is the generalisation of the notion of a 2-variable adjunction, the classical example being the hom/tensor/cotensor trio of functors, to n + 1 functors of n variables.

COMPREHENSIVE MONITORING OF THE TECHNICAL CONDITION OF THE END OUTLET OF THE NEVINNOMYSSKY CANAL, BASED ON THE ASSESSMENT OF RELIABILITY PARAMETERS

open access: yesМелиорация и гидротехника, 2023
Purpose: Carrying out a comprehensive monitoring to assess the technical condition of the reinforced concrete elements of the Nevinnomyssky Canal end outlet, based on the assessment of reliability parameters using non-destructive control methods ...

Applications of the Kleisli and Eilenberg-Moore 2-adjunctions [PDF]

open access: yesCategories and General Algebraic Structures with Applications, 2019
In 2010, J. Climent Vidal and J. Soliveres Tur developed, among other things, a pair of 2-adjunctions between the 2-category of adjunctions and the 2-category of monads.

The Formal Theory of Monads, Univalently [PDF]

open access: yesLogical Methods in Computer Science
We develop the formal theory of monads, as established by Street, in univalent foundations. This allows us to formally reason about various kinds of monads on the right level of abstraction. In particular, we define the bicategory of monads internal to a

Separable functors in corings

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2002
We develop some basic functorial techniques for the study of the categories of comodules over corings. In particular, we prove that the induction functor stemming from every morphism of corings has a left adjoint, called ad-induction functor.
