Eigenvalue estimate for the weighted p-Laplacian

Let M be an n-dimensional closed manifold with metric g, dμ = e ^h(x) dV(x) be the weighted measure and ? _{μ, p} be the weighted p-Laplacian. In this article, we get the lower bound estimate of the first nonzero eigenvalue for the weighted p-Laplacian when the m-dimensional Bakry-émery curvature has a positive lower bound.
