Our purpose of this work is to implement a class of sg^/mml:mover-closed sets, which is property placed among the classes of semiclosed sets and gs-closed sets. The relations with other concepts directly or indirectly joined with generalized closed sets are inspected. In addition, as an application, using the notion of sgmml:mo^/mml:mover-closed sets, we give a brief expansion of a new space named Tsmml:mover accent="true"gmml:mo^/mml:mover-space.
