S. A.K. Kirmani, . Merajuddin, Madhukar Sharma

Abstract


In this paper we study Laplacian spectrum of self-complementary (sc), sc comparability and sc chordal graphs. Some results on Laplacian cospectrality and Laplacian energy are obtained. We also propose two conjectures.


Keywords


L-Cospectral; Laplacian energy
