Abstract

Let T be a tree and let x0 be a vertex of T. T is called a superstar with central vertex x0 if T − x0 is a union of paths. The General Inverse Eigenvalue Problem for certain trees is partially answered. Using this description, some superstars are presented for which the problem of ordered multiplicity lists and the Inverse Eigenvalue Problem are not equivalent.
