摘要

Let \(\Omega \) Ω be a bounded, smooth domain of \(\mathbb {R}^N\) R N , \(N\ge 2\) N 2 . In this paper, we prove some inequalities involving the first Robin eigenvalue of the p-laplacian operator. In particular, we prove an upper bound for the first Robin eigenvalue of nonlinear elliptic operators in terms of the first Dirichlet eigenvalue.
