Additive categories play a fundamental role in mathematics and related disciplines. Given
an additive category equipped with a biadditive functor, one can construct its category of …

The Grothendieck construction and gradings for enriched categories

D Tamaki - arXiv preprint arXiv:0907.0061, 2009 - arxiv.org
The Grothendieck construction is a process to form a single category from a diagram of small
categories. In this paper, we extend the definition of the Grothendieck construction to …

Finite-product-preserving functors, kan extensions, and strongly-finitary 2-monads

GM Kelly, S Lack - Applied Categorical Structures, 1993 - Springer
We study those 2-monads on the 2-category Cat of categories which, as endofunctors, are
the left Kan extensions of their restrictions to the sub-2-category of finite discrete categories …

[PDF][PDF] Universal algebraic completions of right adjoint functors

H Bargenda - Category Theory at Work, 1991 - heldermann.de
We introduce a general concept of an algebraic category, the (E, M)-algebraic categories (A,
i/) over an (E, M)-category X, ie< 7 is a right adjoint and lifts (E, M)-factorizations uniquely …

[PDF][PDF] The functor category

M Prest - CATEGORICAL METHODS IN …, 2012 - personalpages.manchester.ac.uk
Let A be a skeletally small preadditive category. preadditive means that, for each pair, A, B,
of objects of A, the set, A (A, B), we write just (A, B), of morphisms from A to B is equipped …

Reflective and coreflective subcategories

M Cortés-Izurdiaga, S Crivei, M Saorín - Journal of Pure and Applied …, 2023 - Elsevier
Given any additive category C with split idempotents, pseudokernels and pseudocokernels,
we show that a subcategory B is coreflective if, and only if, it is precovering, closed under …

When∏ is Isomorphic to⊕

MC Iovanov - Communications in Algebra®, 2006 - Taylor & Francis
For a category, we investigate the problem of when the coproduct⊕ and the product
functor∏ from I to are isomorphic for a fixed set I, or, equivalently, when the two functors …

[PDF][PDF] Moore categories

D Rodelo - Theory Appl. Categ, 2004 - webdoc.gwdg.de
In 1970, M. Gerstenhaber introduced a list of axioms defining Moore categories in order to
develop the Baer Extension Theory. In this paper, we study some implications between the …
