Reconstructing the Topology on Monoids and Polymorphism Clones of the Rationals
نویسندگان
چکیده
We show how to reconstruct the topology on the monoid of endomorphisms of the rational numbers under the strict or reflexive order relation, and the polymorphism clone of the rational numbers under the reflexive relation. In addition we show how automatic homeomorphicity results can be lifted to polymorphism clones generated by monoids. 2010 Mathematics Subject Classification 08A35 keywords: rationals, automatic homeomorphicity, embedding, endomorphism, polymorphism clone

Detection of Polymorphism in Ancient Tempranillo Clones (Vitis vinifera L.) Using Microsatellite and Retrotransposon Markers
Tempranillo is one of the most widely cultivated grapevine varieties in Spain. After several years of clone selection, some highly recommended old clones have been identified in terms of both their qualitative and production characteristics. This study was designed to discriminate among 28 ancient clones of the cultivar Tempranillo (Vitis vinifera). DNA samples from clones were analysed using t...
متن کاملThe Role of the Scholars` Tradition in Formulating Moral Propositions, with an Emphasis on Muhaqqiq Isfahani`s View
The issue of the source of ethical value is one of the most important issues in the field of metaethics. Moral philosophers have come up with different perspectives on this issue. Some Islamic thinkers, including Muhaqqiqi Isfahani, have considered the rationals` tradition as the formulating cause for moral propositions. This research is intended to emphasize on the viewpoint of Muhaqqiqi Isfah...
متن کاملMicrosatellite Isolation and Characterization in Pomegranate (Punica granatum L.)
Development of microsatellite markers has been an increasing trend in crop genetic studies because oftheir applicability in breeding programs. Here we report the development of inter simple sequencerepeat (SSRs) in pomegranate (Punica granatum L.) using an enrichment method that makes use of magneticbeads. Enriched genomic libraries with AG and ATG microsatellite motifs were c...
متن کاملOn the U-WPF Acts over Monoids
Valdis Laan in [5] introduced an extension of strong flatness which is called weak pullback flatness. In this paper we introduce a new property of acts over monoids, called U-WPF which is an extension of weak pullback flatness and give a classification of monoids by this property of their acts and also a classification of monoids when this property of acts implies others. We also show that regu...
متن کاملOn Regularity of Acts
In this article we give a characterization of monoids for which torsion freeness, ((principal) weak, strong) flatness, equalizer flatness or Condition (E) of finitely generated and (mono) cyclic acts and Condition (P) of finitely generated and cyclic acts implies regularity. A characterization of monoids for which all (finitely generated, (mono) cyclic acts are regular will be given too. We als...
