Abstract
Two decoupling type inequalities for functions of Gaussian vectors are proved. In both cases, it turns out that the case of linear functions is the extreme one. The proofs involve certain properties ofWick’s (Hermite’s) polynomials and a refined version of Schur’s theorem on entrywise product of positive definite matrices.
