ABSTRACT
In this paper we study eigenvalues of the poly-Laplacian with any order on a domain in an n-dimensional unit sphere and obtain estimates for eigenvalues. In particular, the optimal result of Cheng and Yang (Math Ann 331:445–460, 2005) is included in our ones. In order to prove our results, we introduce 2( l + 1) functions a i and b i, for i = 0, 1, . . . , l and two operators μ and η. First of all, we study properties of functions a i and b i and the operators μ and η. By making use of these properties and introducing k free constants, we obtain estimates for eigenvalues.

    The existence problem of Laplacian integral graphs is studied. Let A ( G) denotes the adjacency matrix of graph C with n vertices and D (G) denotes the degree diagonal matrix of graph G. The Laplacian matrix of graph G is L(G) =D(G)-A (G). By studying the Laplacian characteristic polynomial of...
