Let G be an n-vertex (n 3) simple graph embeddable on a surface of Euler genus ฮณ (the number of crosscaps plus twice the number of handles). Denote by the maximum degree of G. In this paper, we first present two upper bounds on the Laplacian spectral radius of G as follows: (i) (ii) If G is 4-conn
