Abstract
This chapter presents probability inequalities for the (dual) norm of a Gaussian vector in \(\mathbb{R}^{p}\). For Gaussian vectors there are ready-to-use concentration Borell, C. inequalities (e.g. Borell, 1975). Here however, results are derived using direct arguments. The extension to for example sub-Gaussian vectors is then easier to read off. Bounds for the supremum are given, for the ℓ 2-norm, and more generally for dual norms of norms generated from a convex cone.
