In this article, we first provide some examples for soft topological polygroups, then define the closure of a soft topological polygroup and state the necessary condition for the closure of a soft topological polygroup to be a soft topological polygroup itself. We present some more characterizations of soft topological polygroups. In particular, explain the relation between soft sets and complete parts in a polygroup. Furthermore, write the different compositions of the closure of soft topological polygroups. Finally, introduce another definition for soft topo-logical polygroups, which we will work on it in future.
