Pointwise Multipliers on Weak Morrey Spaces [PDF]
We consider generalized weak Morrey spaces with variable growth condition on spaces of homogeneous type and characterize the pointwise multipliers from a generalized weak Morrey space to another one.

Smooth pointwise multipliers of modulation spaces [PDF]
Abstract Let 1 < p, q < ∞ and s, r ∈ ℝ. It is proved that any function in the amalgam space W(Hrp(ℝd), ℓ∞), where p' is the conjugate exponent to p and Hrp′ (ℝd) is the Bessel potential space, defines a bounded pointwise multiplication operator in the modulation space Msp,q(ℝd), whenever r > |s ...

Pointwise Multipliers of Weighted BMO Spaces [PDF]
In a recent paper by S. Bloom (Pointwise multipliers of weighted B M O BMO spaces, Proc. Amer. Math. Soc. 105 (1989), 950-960), there are some inaccuracies. In this note, we give a counterexample to his "theorem" and a corrected form with proof under a suitable condition on weights.

Pointwise multipliers on martingale Campanato spaces [PDF]
We introduce generalized Campanato spaces $\mathcal{L}_{p, }$ on a probability space $( ,\mathcal{F},P)$, where $p\in[1,\infty)$ and $ :(0,1]\to(0,\infty)$. If $p=1$ and $ \equiv1$, then $\mathcal{L}_{p, }=\mathrm{BMO}$. We give a characterization of the set of all pointwise multipliers on $\mathcal{L}_{p, }$.

Pointwise multipliers of Calderón‐Lozanovskiǐ spaces
AbstractSeveral results concerning multipliers of symmetric Banach function spaces are presented firstly. Then the results on multipliers of Calderón‐Lozanovskiǐ spaces are proved. We investigate assumptions on a Banach ideal space E and three Young functions φ1, φ2 and φ, generating the corresponding Calderón‐Lozanovskiǐ spaces \documentclass{article}\

Pointwise multipliers for reverse Holder spaces [PDF]
The author gives necessary and sufficient conditions for a positive function to multiply reverse Hölder spaces \(RH_p\) into other reverse Hölder spaces \(RH_q\) when \(0< q\leq p\leq \infty\), and considers local variants and weak reverse Hölder conditions. Let \(\Omega\) be an open subset of \(\mathbb{R}^n\).
