Popis: | We show that for every integer h⩾0, the higher order connectivity index hχ(T) of a starlike tree T (a tree with unique vertex of degree >2) is completely determined by its branches of length ⩽h. As a consequence, we show that starlike trees which have equal h-connectivity index for all h⩾0 are isomorphic. |
