Optimal lower bounds for eigenvalues of linear and nonlinear Neumann problems
In this paper we prove a sharp lower bound for the first non-trivial Neumann eigenvalue μ 1 ( Ω ) for the p -Laplace operator ( p > 1) in a Lipschitz bounded domain Ω in ℝ n . Our estimate does not require any convexity assumption on Ω and …
