In this paper we develop a new method based on Littlewood-Paley's decomposition and heat kernel estimates in integral form, to establish Schauder's estimate for the following degenerate nonlocal equation in with Hölder coefficients: where and is a nonlocal α-stable-like operator with and kernel function κ, which acts on the variable v. As an application, we show the strong well-posedness to the following degenerate stochastic differential equation with Hölder drift b: where is a d-dimensional rotationally invariant and symmetric α-stable process with , and is a -order Hölder continuous function in with and , is a Lipschitz function. Moreover, we also show that for almost all ω, the following random transport equation has a unique -solution: where and is a bounded continuous function of and γ-order Hölder continuous in x uniformly in t with .
