Using a classical Cauchy integral argument, we obtain sharp-weighted inequality for mth order commutator of a square function with $$b \in \text{ BMO }$$ . Also, the $$A_{p}-A_{\infty }$$ estimate for commutators of square functions is proved.

We address an open problem posed by Hästö in 2017 about separability of the mixed Lebesgue-sequence spaces ℓ q ( ⋅ ) ( L p ( ⋅ ) ) \ell ^{q(\cdot )} (L^{p(\cdot )}) .

We investigate the direct and inverse theorems for trigonometric polynomials in the Morrey space $${{\mathcal {M}}}^{p(\cdot ),\lambda (\cdot )}$$ with variable exponents. For this space, we obtain estimates of the K-functional in terms of the modulu

In this paper, the Kantorovich operators $$K_n, n\in \mathbb {N}$$ are shown to be uniformly bounded in Morrey spaces on the closed interval [0, 1]. Also an upper estimate is obtained for the difference $$K_n(f)-f$$ for functions f of regularity of o

In this note, the Morrey spaces and the Sobolev–Morrey spaces are considered. In particular, the K -functional with respect to these spaces is estimated from above and below. As an application, we characterize the Nikol’skii–Besov–Morrey spac
