Abstract

Let Ω ⊂ R m (m ≥ 2) be a bounded domain with piecewise smooth and Lipschitz boundary ∂Ω. Let t and r be two nonnegative integers with t ≥ r +1. In this paper, we consider the variable-coefficient eigenvalue problems with uniformly elliptic differential operators on the left-hand side and (−Δ) r on the right-hand side. Some upper bounds of the arbitrary eigenvalue are obtained, and several known results are generalized.
