On the locality of the pseudovariety DG
of finite categories generated by DG coincides with the pseudovariety lDG of all finite categories whose local monoids all belong to DG. Yet more general statements of this kindThe pseud...

A presentation of a finitely generated submonoid of invertible endomorphisms of the free monoid
An endomorphism of the free monoid is invertible if it is injective and extends to an automorphism of the free group generated by . A simple example: the endomorphism other generator b. We give a monoi...

Finite-valued dually residuated lattice-ordered monoids
We study values in dually residuated lattice-ordered monoids (DRl-monoids) especially if the ideal lattice is a member of the class IRN of algebraic distributive lattices whose compact elemets form a relatively normal subla...

Generalized Eilenberg Theorem: Varieties of Languages in a Category
For finite automata as coalgebras in a category C, we study languages they accept and varieties of such languages. This generalizes Eilenberg's concept of monoids and varieties of regular languages. In our gene...

On the Structure of Finite Integral Commutative Residuated Chains.
Among the class of finite integral commutative residuated chains (ICRCs), we this condition regular. Then we discuss the structure of finite regular ICRCs. Finally, we prove that the class of regular members generate a stri...

Free monoids and generalized metric spaces
Let A be an ordered alphabet, A* be the free monoid over A ordered of concatenation, this set is a monoid. We show that the submonoid F degrees(A*) := F(A*) {empty set} is free. The MacNeille completion N(A*) of A*...

Algorithm for Generating Finite Totally Ordered Monoids
The semantics of fuzzy logic is typically based on negative totally ordered monoids. This contribution describes an algorithm generating in a step-wise fashion all finite structures of this kind....
