Abstract
Transformation monoids carry a canonical topology --- the topology of point-wise convergence. A closed transformation monoid is said to have automatic homeomorphicity with respect to a class of structures, if every monoid-isomorphism of to the endomorphism monoid of a member of is automatically a homeomorphism. In this paper we show automatic homeomorphicity-properties for the monoid of non-decreasing functions on the rationals, the monoid of non-expansive functions on the Urysohn space and the endomorphism-monoid of the countable universal homogeneous poset.
