Now the research of eigenvalues of Riemannian manifolds has been an important fields in analysis of manifolds. It has many applications in mathematics, physics and so on. Let Ω be a bounded domain in an n-dimensional Riemannian manifold Mn andâ†'n be the unit outward normal vector field of OM. The well-known eigenvalues problem is called a biharmonic operator with weight problem. Hereâ–³is the Laplacian of Mn, V is the positive and bounded function on Mn, and p is a weight function.In this paper, we discuss the eigenvalues of the biharmonic operator with a weight on compact Riemannian manifolds with boundary (?)M (possibly empty), and prove a general inequality for them. As its application, we obtain several universal inequalities for such biharmonic operators. |
