Abstract
Let be a monoid which is generated by the partial shift of the set of positive integers and its inverse partial shift . In this paper we prove that if is a submonoid of the monoid of all partial cofinite isometries of positive integers which contains as a submonoid then every Hausdorff locally compact shift-continuous topology on with adjoined zero is either compact or discrete. Also we show that the similar statement holds for a locally compact semitopological semigroup with an adjoined compact ideal.
