Estimates for Eigenvalues of Poly-Harmonic Operators
Guoxin Wei, Lingzhong Zeng · Advanced Nonlinear Studies · 2016
Abstract In this paper, we study the eigenvalues of the poly-Laplacian with arbitrary order on a bounded domain in an n -dimensional Euclidean space and we obtain a lower bound which generalizes the results due to Cheng and Wei [5] and gives an improvement of the results due to Cheng, Qi and Wei [3].
