Description

We present a Chevet-type inequality for subsexpontial Weibull processes and show how
it may be applied to derive two-sided bounds for operator \ell_p to \ell_q norms of random
rectangular matrices with iid Weibull entries. We also discuss lower and upper bounds
for operator norms of other iid matrices. The talk is based on a joint work with Marta Strzelecka.
