Finite automata for Schreier graphs of virtually free groups

Pedro Silva, Xaro Soler-Escrivà, Enric Ventura

The Stallings construction for finitely generated subgroups of free groups is generalized by introducing the concept of Stallings section, which allows an eficient computation of t…

Some operators that preserve the locality of a pseudovariety of semigroups

Alfredo Costa, Ana Escada

It is shown that if V is a local monoidal pseudovariety of semigroups, then K(m)V, D(m)V and LI(m)V are local. Other operators of the form Z(m)(_) are considered. In the process, r…

Amalgams of inverse semigroups and reversible two-counter machines

Emanuele Rodaro, Pedro V. Silva

We show that the word problem for an amalgam of inverse semigroups may be undecidable even if we assume and (and therefore ) to have finite $\m…

Further results on monoids acting on trees

John Rhodes, Pedro V. Silva

This paper further develops the theory of arbitrary semigroups acting on trees via elliptic mappings. A key tool is the Lyndon-Chiswell length function L for the semigroup S which…
