Abstract

We use Cram\'er-Chernoff type estimates in order to study the Calder\'on-Zygmund structure of the kernels IDaI(ω)ψI(x)ψI(y)\sum_{I\in\mathcal{D}}a_I(\omega)\psi_I(x)\psi_I(y) where aIa_I are subgaussian independent random variables and {ψI:ID}\{\psi_I: I\in\mathcal{D}\} is a wavelet basis where D\mathcal{D} are the dyadic intervals in R\mathbb{R}. We consider both, the cases of standard smooth wavelets and the case of the Haar wavelet.
