UDC 517.9Two graphs are said to be $Q$-cospectral if they have the same signless Laplacian spectrum.A graph is said to be DQS if there are no other nonisomorphic graphs $Q$-cospectral with it. A tree is called double starlike if it has exactly two vertices of degree greater than 2.Let $H_n(p,q)$ wit...
