Functional Inequalities for Stable-Like Dirichlet Forms
arXiv:1205.4508
Abstract
Let such that $μ_V(\d x):= \e^{-V(x)}\,\d x$ is a probability measure, and let . Explicit criteria are presented for the -stable-like Dirichlet form $$\E_{å,V}(f,f):= \int_{\R^d\times\R^d} \ff{|f(x)-f(y)|^2}{|x-y|^{d+α}}\,\d y\,\e^{-V(x)}\,\d x$$ to satisfy Poincaré-type (i.e., Poincaré, weak Poincaré and super Poincaré) inequalities. As applications, sharp functional inequalities are derived for the Dirichlet form with having some typical growths. Finally, the main result of \cite{MRS} on the Poincaré inequality is strengthened
