On unitary Cauchy filters on topological monoids [PDF]

open access: diamondTopological Algebra and its Applications, 2013
AbstractFor Hausdorff topological monoids, the concept of a unitary Cauchy net is a generalization of the concept of a fundamental sequence of reals. We consider properties and applications of such nets and of corresponding filters and prove, in particular, that the underlying set of a given monoid, endowed with the family of such filters, forms a ...

On locally compact semitopological O-bisimple inverse ω-semigroups

open access: yesTopological Algebra and its Applications, 2018
We describe the structure of Hausdorff locally compact semitopological O-bisimple inverse ω- semigroups with compact maximal subgroups. In particular, we show that a Hausdorff locally compact semitopological O-bisimple inverse ω-semigroup with a compact ...

Completions and fibrations for topological monoids [PDF]

open access: bronzeTransactions of the American Mathematical Society, 1993
We show that, for a certain class of topological monoids, there is a homotopy equivalence between the homotopy theoretic group completion M + {M^ + } of a monoid M M in that class and the topologized Grothendieck group M ~ \tilde M

Topological finiteness properties of monoids. Part 1: Foundations

open access: green, 2017
We initiate the study of higher dimensional topological finiteness properties of monoids. This is done by developing the theory of monoids acting on CW complexes.

Toposes of Topological Monoid Actions [PDF]

open access: diamondCompositionality, 2023
We demonstrate that categories of continuous actions of topological monoids on discrete spaces are Grothendieck toposes. We exhibit properties of these toposes, giving a solution to the corresponding Morita-equivalence problem. We characterize these toposes in terms of their canonical points.

Subordinators on Feller Topological Monoids

open access: green, 2022
We investigate a class of topological monoids with a suitable family of characters which we call Feller topological monoids. We extend the classical notion of subordinators to subordinators on Feller topological monoids. Under suitable assumptions, we prove a Lévy-Khintchine type representation for such subordinators.

Topological groups with co-monoid structures [PDF]

open access: bronzeGlasgow Mathematical Journal, 1977
The Eckman–Hilton duality [4] reverses arrows in diagrams, turns products to co-products, and multiplications to co-multiplications, etc. In accordance with this process, Kan [5] obtained the dual of a monoid structure in the category of groups. In this way, we obtain co-monoid structures on topological groups. The main result of this paper is that for

Endomorphism monoids and topological subgraphs of graphs

open access: bronzeJournal of Combinatorial Theory, Series B, 1980
AbstractWe prove, that, given a finite graph Y there exists a finite monoid (semigroup with unity) M such that any graph X whose endomorphism monoid is isomorphic to M contains a subdivision of Y. This contrasts with several known results on the simultaneous prescribability of the endomorphism monoid and various graph theoretical properties of a graph.

Non-archimedean topological monoids

open access: hybridSemigroup Forum
AbstractWe say that a topological monoid S is left non-archimedean (in short: l-NA) if the left action of S on itself admits a proper S-compactification $$\nu :S \hookrightarrow Y$$ ν : S ↪ Y such ...
