Rademacher-Gaussian tail comparison for complex coefficients and related problems

Probability 2022-03-15 v1

Abstract

We provide a generalisation of Pinelis' Rademacher-Gaussian tail comparison to complex coefficients. We also establish uniform bounds on the probability that the magnitude of weighted sums of independent random vectors uniform on Euclidean spheres with matrix coefficients exceeds its second moment.
