Every group-embeddable monoid arises as the bimorphism monoid of some graph
Thomas D. H. Coleman, Isaac K. Dilley
Generalizing results of Frucht and de Groot/Sabidussi, we demonstrate that every group-embeddable monoid is isomorphic to the bimorphism monoid of some graph.
The Todd-Coxeter Algorithm for Semigroups and Monoids
T. D. H. Coleman, J. D. Mitchell, F. L. Smith +1
In this paper we provide an account of the Todd-Coxeter algorithm for computing congruences on semigroups and monoids. We also give a novel description of an analogue for semigroup…
Two Fraïssé-style theorems for homomorphism-homogeneous relational structures
Thomas D. H. Coleman
In this paper, we state and prove two Fraïssé-style results that cover existence and uniqueness properties for twelve of the eighteen different notions of homomorphism-homogeneity…
Permutation monoids and MB-homogeneity for graphs and relational structures
Thomas D. H. Coleman, David M. Evans, Robert D. Gray
In this paper, we investigate the connection between infinite permutation monoids and bimorphism monoids of first-order structures. Taking our lead from the study of automorphism g…
Inertial Chow rings of toric stacks
Thomas Coleman, Dan Edidin
For any vector bundle on a toric Deligne-Mumford stack $\ix$ the formalism of \cite{EJK:16} defines two intertial products and on the Chow group…
