摘要
The first eigenvalue lambda of the p-Laplacian operator with zero Dirichlet boundary condition in bounded domain Omega subset of R-n, n >= 2, p > 1 is considered. A lower bound for lambda is obtained by means of Hardy inequality with double singular kernel. Comparison with analytical and numerical estimates from below in the ball for the first eigenvalue is shown.
