    In this paper, we consider the eigenvalue problem of fourth-order weighted polynomial operator on bounded domains in a hyperbolic space, and get a general inequality. By using this inequality, we obtain some universal inequalities of the eigenvalues. Moreover, by these universal inequalities, we can get some results for the biharmonic operator.
