Weightable quasi-metric semigroups and semilattices
In [Sch00] a bijection has been established, for the case of semilattices, between invariant partial metrics and semivaluations. Semivaluations are a natural generalization of valuations on lattices to the context of semilattices and arise in many different contexts in Quantitative Domain Theory ([Sch00]). Examples of well known spaces which are semivaluation spaces are the Baire quasi-metric s...
متن کاملTight Representations of Semilattices and Inverse Semigroups
By a Boolean inverse semigroup we mean an inverse semigroup whose semilattice of idempotents is a Boolean algebra. We study representations of a given inverse semigroup S in a Boolean inverse semigroup which are tight in a certain well defined technical sense. These representations are supposed to preserve as much as possible any trace of Booleannes present in the semilattice of idempotents of ...
متن کاملcompactifications and representations of transformation semigroups
this thesis deals essentially (but not from all aspects) with the extension of the notion of semigroup compactification and the construction of a general theory of semitopological nonaffine (affine) transformation semigroup compactifications. it determines those compactification which are universal with respect to some algebric or topological properties. as an application of the theory, it is i...
15 صفحه اولThe Structure of Endomorphism monoids of Strong semilattices of left simple semigroups
Endomorphism monoids have long been of interest in universal algebra and also in the study of particular classes of algebraic structures. For any algebra, the set of endomorphisms is closed under composition and forms a monoid (that is, a semigroup with identity). The endomorphism monoid is an interesting structure from a given algebra. In this thesis we study the structure and properties of th...
متن کاملSemilattices and Ramsey Property
We consider S, the class of nite semilattices; T , the class of nite treeable semilattices; and Tm, the subclass of T which contains trees with branching bounded by m. We prove that ES, the class of nite lattices with linear extensions, is a Ramsey class. We calculate Ramsey degrees for structures in S, T and Tm. In addition to this we give a topological interpretation of our results and we ...
