A Variational Estimate for Paraproducts
نویسندگان
چکیده
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.

Multilinear Paraproducts Revisited
We prove that mutlilinear paraproducts are bounded from products of Lebesgue spaces L1 ×· · ·×Lm+1 to Lp,∞, when 1 ≤ p1, . . . , pm+1 <∞, 1/p1+· · ·+1/pm+1 = 1/p. We focus on the endpoint case when some indices pj are equal to 1, in particular we obtain the new endpoint estimate L× · · · ×L → L1/(m+1),∞. In memory of Nigel Kalton
متن کاملParaproducts in One and Several Parameters
For multiparameter bilinear paraproduct operators B we prove the estimate B : L × L 7→ L, 1 < p, q ≤ ∞. Here, 1/p+ 1/q = 1/r and special attention is paid to the case of 0 < r < 1. (Note that the families of multiparameter paraproducts are much richer than in the one parameter case.) These estimates are the essential step in the version of the multiparameter Coifman-Meyer theorem proved by C. M...
متن کاملBilinear Paraproducts Revisited
Boundedness properties for bilinear paraproducts on several function spaces are presented. The methods are based on the realization of paraproducts as bilinear Calderón-Zygmund operators and the molecular characterization of function spaces. This provides a unified approach for the study of paraproducts, recovering some know results and establishing several new.

We consider the dyadic paraproducts πb associated with Mn valued functions b, and show that the L(Mn) norm of b does not dominate ||πb||L2(l2n)→L2(l2n) uniformly over n. We also consider paraproducts associated with noncommutative martingales...

Here T is the unit circle and M is a tracial von Neumann algebra. We prove that their boundedness on L(T, L(M)) for some 1 < p < ∞ implies their boundedness on L(T, L(M)) for all 1 < p ...
