A Variational Estimate for Paraproducts
We show variational estimates for paraproducts, Theorems 1.2 and 1.3, which can be viewed as bilinear generalizations of Lépingle’s variational estimates for martingale averages or scaled families of convolution operators. The heart of the matter is the case of low variation exponents, 1 < r ≤ 2.
متن کاملUniform estimates for some paraproducts
We establish L × L to L estimates for some general paraproducts, which arise in the study of the bilinear Hilbert transform along curves.
متن کاملUniform Estimates on Paraproducts
We prove uniform L estimates (Theorem 1.1) for a family of paraproducts and corresponding maximal operators.
متن کاملUniform estimates for paraproducts and related multilinear multipliers
In this paper, we prove some uniform estimates between Lebesgue and Hardy spaces for operators closely related to the multilinear paraproducts on Rd. We are looking for uniformity with respect to parameters, which allow us to disturb the geometry and the metric on Rd.
متن کاملWeighted Estimates for Dyadic Paraproducts and T -haar Multipliers with Complexity (m,n)
We extend the definitions of dyadic paraproduct and t-Haar multipliers to dyadic operators that depend on the complexity (m, n), for m and n natural numbers. We use the ideas developed by Nazarov and Volberg in [NV] to prove that the weighted L(w)-norm of a paraproduct with complexity (m, n), associated to a function b ∈ BMO, depends linearly on the A2-characteristic of the weight w, linearly o...
