Uniform large deviations of fractional stochastic equations with polynomial drift on unbounded domains

In this paper, we first prove a uniform contraction principle for verifying the uniform large deviation principles of locally Holder continuous maps in Banach spaces. We then show the local Holder continuity of the solutions of a class of fractional parabolic equations with polynomial drift of any order defined on Double-struck capital R-n. We finally establish the large deviation principle of the fractional stochastic equations uniformly with respect to bounded initial data, despite the solution operators are not compact due to the non-compactness of Sobolev embeddings on unbounded domains.
