Let G be a connected graph of order n with Laplacian eigenvalues μ1 ≥ μ2 ≥ . . .≥ μn−1 > μn = 0. The Kirchhoff index of G is defined as Kf = Kf(G) = n∑n−1 k=1 1/μk. In this paper. we give lower and upper bounds on Kf of graphs in terms on n, number of edges, maximum degree, and number of spanning trees. Moreover, we present lower and upper bounds on the Nordhaus–Gaddum-type result for the Kirch...

Abstract Dynamic problems of thin linearly elastic Kirchhoff–Love-type circular cylindrical shells having geometrical, and inertial properties densely periodically varying in circumferential direction ( uniperiodic ) are studied. In order to take into account the effect a cell size on global dynamic behaviour such length-scale ), new mathematical averaged non-asymptotic model is formulated. Thi...
