A tail estimate for empirical processes of multivariate Gaussian under general dependence

In this paper, we discuss the convergence rate of empirical processes of Gaussian processes for a large class of function families. Our main goal is to show that the tail of the uniform norm of the empirical processes can be dominated by polynomials. We put forward the properties of Hermite polynomials which play a crucial role in the proof of main theorems. At the end of the paper, we show the expectation of the random quantity converging to zero at a more rapid rate n^{-1/2+ε} than ever shown rate n^{-1/3}.
