Characterizations of a class of Musielak--Orlicz BMO spaces via commutators of Riesz potential operators

Yanyan Han, Hongwei Huang, Jinghan Shao +1

The fractional integral operators $I_{α}$ can be used to characterize the Musielak--Orlicz Hardy spaces. This paper shows that for $b \in BMO (R^{n})$ , the commutators $[b,I_…

Sparse dominations and weighted variation inequalities for singular integrals and commutators

Yongming Wen, Huoxiong Wu, Qingying Xue

This paper gives the pointwise sparse dominations for variation operators of singular integrals and commutators with kernels satisfying the $L^{r}$ -Hörmander conditions. As applicati…
