چکیده
|
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. © 2014 lijun yu et al.
