Abstract
Let \(V\in C^2(\mathbb{R }^d)\) such that \(\mu _V(\text{ d }x):= \text{ e }^{-V(x)}\,\text{ d }x\) is a probability measure, and let \(\alpha \in (0,2)\). Explicit criteria are presented for the \(\alpha \)-stable-like Dirichlet form
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 \(V\) having some typical growths. Finally, the main result of [15] on the Poincaré inequality is strengthened.
