ISBN: 978-0-7695-3507-4
In this paper, the double star like graphs $T(p,n,p-2)$, which is coalesced from two stars $K_{1,p}$ and $K_{1,p-2}$ by identifying the center of $K_{1,p}$ with one end of a path $P_n$ and the center of $K_{1,p-2}$ with the other end of $P_n$, is determined by its Laplacian spectrum.
Index Terms:
Double starlike graph, Laplacian spectrum, cospectral graphs
