Finite Generation and Presentability of Wreath Products of Monoids
This paper gives necessary and sufficient conditions for the restricted wreath product of two monoids to be finitely generated or finitely presented.
متن کاملOn Finite Generation and Presentability of Schützenberger Products
The finite generation and presentation of Schützenberger products of semigroups are investigated. A general necessary and sufficient condition is established for finite generation. The Schützenberger product of two groups is finitely presented as an inverse semigroup if and only if the groups are finitely presented, but is not finitely presented as a semigroup unless both groups are finite. 200...
متن کاملOn Finite Presentability of Group F/[m, N]
The characterization of normal subgroups M , N of free group F for which the quotient group F/[M, N ] is finitely presented is given.
متن کاملFinite Presentability of HNN Extensions of Inverse Semigroups
HNN extensions of inverse semigroups, where the associated inverse subsemigroups are order ideals of the base, are defined by means of a construction based upon the isomorphism between the categories of inverse semigroups and inductive groupoids. The resulting HNN extension may conveniently be described by an inverse semigroup presentation, and we determine when an HNN extension with finitely g...
متن کاملFinite Presentability and Isomorphism of Cayley Graphs of Monoids
Two finitely generated monoids are constructed, one finitely presented the other not, whose (directed, unlabelled) Cayley graphs are isomorphic.
