Classifying Spaces of Topological Monoids and Categories

American Journal of Mathematics, 1984
This article explores homology and weak homotopy equivalences between classifying spaces of topological categories and discrete categories. Many recent results have dealt with this phenomenon: e.g. for any space X there is a discrete group and a homology equivalence BG\(\to X\) [\textit{D. Kan} and \textit{W.

Monoidal Topology

2014
Monoidal Topology describes an active research area that, after various past proposals on how to axiomatize 'spaces' in terms of convergence, began to emerge at the beginning of the millennium. It combines Barr's relational presentation of topological spaces in terms of ultrafilter convergence with Lawvere's interpretation of metric spaces as small ...

Retractions and retracts of free topological monoids

International Journal of Computer Mathematics, 2006
Some topological properties of retracts, semiretracts and retractions which make a link between the topological notion of a retract with its pure algebraic analogon in free monoids are presented.

Topological Hopf Algebras and Braided Monoidal Categories

Applied Categorical Structures, 1998
Let \({\mathcal C}\) be a small monoidal category, \(K\) a Dedekind domain. The author first notes that any exact faithful monoidal functor from \({\mathcal C}\) to the category of finite rank projective \(K\)-modules factors through a functor from \({\mathcal C}\) to the category of continuous modules over a topological \(K\)-bialgebra \(A\).
