From Yoneda to Topoi morphisms
Eduardo J. Dubuc
In this note we show how two fundamental results in Topos theory follow by repeated use of Yoneda's Lemma, the formalism of natural transformations and very basic category theory.…
The 2-localization of a model category
Eduardo J. Dubuc, Jaqueline Girabel
In this paper we study a 2-dimensional version of Quillen's homotopy category construction. Given a category and a class of morphisms containin…
Column symmetric polynomials
Eduardo Dubuc, Anders Kock
We study the polynomial algebra (over a ring containing the rationals) in an n by m matrix of variables, and subject to the relation that says that the product of any two variables…
A localization of bicategories via homotopies
M. E. Descotte, E. J. Dubuc, M. Szyld
Given a bicategory C and a family W of arrows of C, we give conditions on the pair (C,W) that allow us to construct the bicategorical localization with respect to W by dealing only…
A construction of certain weak colimits and an exactness property of the 2-category of categories
M. E. Descotte, E. J. Dubuc, M. Szyld
Given a 2-category , a -functor and a distinguished 1-subcategory containing all t…
Some remarks on infinitesimals in MV-algebras
Eduardo J. Dubuc, Jorge Zilber
Replacing by the whole ideal of infinitesimals yields a weaker notion of \emph{archimedean element} that we call \emph{quasiarchimedean}. It is known that semisimple MV-alg…
