Graphs determined by their (signless) Laplacian spectra

Graphs determined by their (signless) Laplacian spectra

, where n ≥ 2c + 1 and c ≥ 0. In this paper, S(n, c) and its complement are shown to be determined by their Laplacian spectra, respectively.Moreover, we also prove that S(n, c) and its complement are determined by their signless Laplacian spectra, respectively.
