For a tree T and an integer k⩾1, it is well known that the kth power Tk of T is strongly chordal and hence has a strong elimination ordering of its vertices. In this note we obtain a complete characterization of strongly simplicial vertices of Tk, thereby characterizing all strong elimination orderings of the vertices of Tk. |
