Quantitative Version of a Silverstein’s Result

Chapter
Part of the Lecture Notes in Mathematics book series (LNM, volume 2116)

Abstract

We prove a quantitative version of a Silverstein’s Theorem on the 4-th moment condition for convergence in probability of the norm of a random matrix. More precisely, we show that for a random matrix with i.i.d. entries, satisfying certain natural conditions, its norm cannot be small.
