Query: Half Inverse Sturm-Liouville Problem on Three-Star Graph with a
  Discontinuity   We consider the inverse Sturm-Liouville problem with one discontinuous point
on three-star graph, we deduced the distribution of the eigenvalues, and proved
that one spectrum could uniquely determine the unknown potential and jump
information when we know the whole potentials on two edges and half potential
on another edge.
