k-TRANSFORMATION SEMIGROUPS OF TILSON
Let Q be a finite set and let k be a non negative integer. A (partial) function f: Q + Q is a k-map if ]sf’] < k, Vq E Q. A transformation semigroupx = (Q, S) is a k-t.s. if each s ES is a k-map. Let TS be the collection of all (finite) transformation semigroups and let c: TS + N be the complexity function. For background on complexity see [2]. The main theorem of this paper shows that if X is ...
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 اولUNIVERSAL COMPACTIFICATIONS OF TRANSFORMATION SEMIGROUPS
We extend the notion of semigroup compactification to the class of transformation semigroups, and determine the compactifications which are universal with respect to some topological properties.
متن کاملTRANSFORMATION SEMIGROUPS AND TRANSFORMED DIMENSIONS
In the transformation semigroup (X, S) we introduce the height of a closed nonempty invariant subset of X, define the transformed dimension of nonempty subset S of X and obtain some results and relations.

in the transformation semigroup (x, s) we introduce the height of a closed nonempty invariant subset of x, define the transformed dimension of nonempty subset s of x and obtain some results and relations.
