Published in 2019 at "Journal of Fourier Analysis and Applications"

DOI: 10.1007/s00041-019-09676-y

Abstract: The purpose of this article is to provide an alternative proof of the weak-type $$\left( 1,\ldots ,1;\frac{1}{m}\right) $$1,…,1;1m estimate for m-multilinear Calderón–Zygmund operators on $${\mathbb {R}}^n$$Rn first proved by Grafakos and Torres. Subsequent proofs in… read more here.

Published in 2019 at "Journal of Mathematical Analysis and Applications"

DOI: 10.1016/j.jmaa.2018.11.006

Abstract: Abstract This paper is devoted to studying the vector-valued estimates for the limiting weak-type behaviors of singular and fractional integrals as well as maximal operators with homogeneous kernels. Under the assumptions of that the kernels… read more here.
