M. Dettlaff , M. Lemańska , Jerzy Topp , Paweł Żyliński


In this paper, for a graph G and a family of partitions P of vertex neighborhoods of G, we define the general corona G∘P of G. Among several properties of this new operation, we focus on application general coronas to a new kind of characterization of trees with the domination subdivision number equal to 3.
