Commutators of integral operators with functions in Campanato spaces on Orlicz-Morrey spaces

Minglei Shi, Ryutaro Arai, Eiichi Nakai

We consider the commutators $[b, T]$ and $[b, I_{ρ}]$ on Orlicz-Morrey spaces, where $T$ is a Calderón-Zygmund operator, $I_{ρ}$ is a generalized fractional integral operator and $b$ is…

Generalized fractional integral operators and their commutators with functions in generalized Campanato spaces on Orlicz spaces

Minglei Shi, Ryutaro Arai, Eiichi Nakai

We investigate the commutators $[b, I_{ρ}]$ of generalized fractional integral operators $I_{ρ}$ with functions $b$ in generalized Campanato spaces and give a necessary and sufficient c…

Generalized fractional maximal and integral operators on Orlicz and generalized Orlicz--Morrey spaces of the third kind

Fatih Deringoz, Vagif S. Guliyev, Eiichi Nakai +2

In the present paper, we will characterize the boundedness of the generalized fractional integral operators $I_{ρ}$ and the generalized fractional maximal operators $M_{ρ}$ on Orlicz s…

Pointwise multipliers on weak Orlicz spaces

Ryota Kawasumi, Eiichi Nakai

We characterize the pointwise multipliers from a weak Orlicz space to another weak Orlicz space.
