摘要
A tree is called starlike if it has exactly one vertex of degree greater than two, In [2] it was proved that two starlike trees are cospectral if and only if they are isomorphic. A tree is called double starlike if it has exactly two adjacent vertices of degree greater than two. We prove here that there exist no two cospectral non-isomorphic symmetric double starlike trees. © 2006 Korean Society for Computational & Applied Mathematics and Korean SIGCAM.
