Abstract: Let W(n; q, m1, m2) be the unicyclic graph with n vertices obtained by attaching two paths of lengths m1 and m2 at two adjacent vertices of cycle Cq. Let U(n; q, m1, m2, …, ms) be the unicyclic graph with n vertices obtained by attaching s paths of lengths m1, m2, …, ms at the same vertex of cycle Cq. In this paper, we prove that W(n; q, m1, m2) and U(n; q, m1, m2, …, ms) are determined by their Laplacian spectra when q is even.
