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 …

In this thesis, we consider questions relating to automorphisms and endomorphisms of
countable, relational first-order structures M, with a particular emphasis on bimorphism …

A topological group is a group equipped with a topology so that the group operations are
continuous. The symmetries (or automorphisms) of any given geometric object have a …

We investigate the structure of the monoid of endomorphisms of the ordered set (ℚ,≤) of
rational numbers. We show that for any countable linearly ordered set Ω, there are …
