Orthogonal completions of the polycyclic monoids

M V Lawson


Abstract

We introduce the notion of an orthogonal completion of an inverse monoid with zero. We show that the orthogonal completion of the polycyclic monoid on n generators is isomorphic to the inverse monoid of right ideal isomorphisms between the finitely generated right ideals of the free monoid on n generators, and so we make a direct connection with the Thompson groups $V_{n,1}$
