Boundedness of intrinsic square functions and commutators on generalized central Morrey spaces

In this paper, the authors establish the boundedness for a large class of intrinsic square functions $\mathcal{G}_α$, $g_α$, $g^{\ast}_{\tildeλ,α}$ and their commutators $[b,\mathcal{G}_α]$, $[b,g_α]$ and $[b,g^{\ast}_{\tildeλ,α}]$ generated with $λ$-central $BMO$ functions $b\in CBMO^{p,λ}(\mathbb{R}^{n})$ on generalized central Morrey spaces $\mathcal{B}^{q,φ}(\mathbb{R}^{n})$ for $1<q<\infty,0<α\leq1$, respectively. All of the results are new even on the central Morrey spaces $\mathcal{B}^{q,λ}(\mathbb{R}^{n})$.
