compactifications 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...

Partial Semigroups and Convolution Algebras

Partial Semigroups are relevant to the foundations of quantum mechanics and combinatorics as well as to interval and separation logics. Convolution algebras can be understood either as algebras of generalised binary modalities over ternary Kripke frames, in particular over partial semigroups, or as algebras of quantale-valued functions which are equipped with a convolution-style operation of mu...

Independence Algebras, Basis Algebras and Semigroups of Quotients

We show that if A is a stable basis algebra satisfying the distributivity condition, then B is a reduct of an independence algebra A having the same rank. If this rank is finite, then the endomorphism monoid of B is a left order in the endomorphism monoid of A.

Crossed Products by Semigroups of Endomorphisms and the Toeplitz Algebras of Ordered Groups

Let I+ be the positive cone in a totally ordered abelian group F. We construct crossed products by actions of J+ as endomorphisms of C*algebras, and give criteria which ensure a given representation of the crossed product is faithful. We use this to prove that the C*-algebras generated by two semigroups V, W: I+ -+ B(H) of nonunitary isometrics are canonically isomorphic, thus giving a new, sel...

On varieties of semigroups and unary algebras∗†

The elementary result of Variety theory is Eilenberg’s Variety theorem which was motivated by characterizations of several families of string languages by syntactic monoids or semigroups, such as Schützenberger’s theorem connecting star-free languages and aperiodic monoids. Eilenberg’s theorem has been extended in various directions. For example, Thérien involved varieties of congruences on fre...
