Pointwise multipliers between weighted copson and cesàro function spaces
Mathematica Slovaca, 2019 Abstract In this paper the solution of the pointwise multiplier problem between weighted Copson function spaces Copp1,q1(u1, v1) and weighted Cesàro function spaces Cesp2,q2(u2, v2) is presented, where p1, p2, q1, q2 ∈ (0, ∞), p2 ≤ q2 and u1, u2, v1, v2 are weights on (0, ∞).

Multipliers in Holomorphic Mean Lipschitz Spaces on the Unit Ball [PDF]
Abstract and Applied Analysis, 2012 For 1≤p≤∞ and s>0, let Λsp be holomorphic mean Lipschitz spaces on the unit ball in ℂn. It is shown that, if s>n/p, the space Λsp is a multiplicative algebra. If s>n/p, then the space Λsp is not a multiplicative algebra.

Pointwise multipliers on weighted BMO spaces [PDF]
Studia Mathematica, 1997 Summary: Let \(E\) and \(F\) be spaces of real- or complex-valued functions defined on a set \(X\). A real- or complex-valued function \(g\) defined on \(X\) is called a pointwise multiplier from \(E\) to \(F\) if the pointwise product \(fg\) belongs to \(F\) for each \(f\in E\).

Pointwise multipliers in Hardy-Orlicz spaces, and interpolation
MATHEMATICA SCANDINAVICA, 2010 We study multipliers of Hardy-Orlicz spaces ${\mathcal H}_{\Phi}$ which are strictly contained between $\bigcup_{p>0}H^p$ and so-called "big" Hardy-Orlicz spaces. Big Hardy-Orlicz spaces, carrying an algebraic structure, are equal to their multiplier algebra, whereas in classical Hardy spaces $H^p$, the multipliers reduce to $H^{\infty}$.

Pointwise multipliers between spaces of analytic functions
Quaestiones Mathematicae, 2023 A Banach space X of analytic function in D, the unit disc in C, is said to be admissible if it contains the polynomials and convergence in X implies uniform convergence in compact subsets of D.If X and Y are two admissible Banach spaces of analytic functions in D and g is a holomorphic function in D, g is said to be a multiplier from X to Y if g · f ...

Pointwise multipliers of Calderón‐Lozanovskiǐ spaces
Mathematische Nachrichten, 2012 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}\

From refined estimates for spherical harmonics to a sharp multiplier theorem on the Grushin sphere [PDF]
, 2019 We prove a sharp multiplier theorem of Mihlin–Hörmander type for the Grushin operator on the unit sphere in R 3 , and a corresponding boundedness result for the associated Bochner–Riesz means.

Pointwise multipliers for reverse Holder spaces [PDF]
Studia Mathematica, 1994 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 \(\mathbb{R}^n\).

Forward integration, convergence and non-adapted pointwise multipliers [PDF]
Infinite Dimensional Analysis, Quantum Probability and Related Topics, 2015 In this paper we study the forward integral of operator-valued processes with respect to a cylindrical Brownian motion. In particular, we provide conditions under which the approximating sequence of processes of the forward integral, converges to the stochastic integral process with respect to Sobolev norms of smoothness α < 1/2. This result will be
