Acta Mathematica Sinica,English Series 2017年 第7期33卷 1011-1020页
作者: Hong Hai LIU School of Mathematics and information Science He'nan Polytechnic UniversityJiaozuo 454003P.R.China
Abstract In this paper, we give counterexamples to show that variation and oscillation operators related to rough truncations of the Hilbert transform are not bounded from H1 to L1, and prove variation, oscillation an... 详细信息

Oscillation and variation for Riesz transform in setting of Bessel operators on H1 and BMO
收藏 引用
Frontiers of Mathematics in China 2020年 第4期15卷 617-647页
作者: Xiaona CUI Jing ZHANG College of Mathematics and Information Science Henan Normal UniversityXinxiang 453007China School of Mathematics and Statistics Yili Normal UniversityYining 835000China
Letλ〉0,and let the Bessel operator△λ:=-d2/dx2-2λ/x d/dx defined on R+:=(0,∞).We show that the oscillation andρ-variation operators of the Riesz transform R△λassociated with△λare bounded on BMO(R+,dmλ),wher... 详细信息
