The Generalized Grand Wiener Amalgam Spaces and the boundedness of Hardy-Littlewood maximal operators

Abstract

In \cite{g5}, we defined and investigated the grand Wiener amalgam space $W(L^{p),θ_1}(Ω), L^{q),θ_2}(Ω))$ , where $1 0, θ_2>0$, $Ω\subset\mathbb R^{n} $ and the Lebesgue measure of $Ω$ is finite. In the present paper we generalize this space and define the generalized grand Wiener amalgam space $W(L_{a}^{p)}(\mathbb R^{n}), L_{b}^{q)}(\mathbb R^{n})),$ where $L_{a}^{p)}(\mathbb R^{n})$ and $L_{b}^{q)}(\mathbb R^{n}),$ are the generalized grand Lebesgue spaces, (see \cite{u}, \cite{su3}). Later we investigate some basic properties. Next we study embeddings for these spaces and we discuss boundedness and unboundedness of the Hardy-Littlewood maximal operator between some generalized grand Wiener amalgam spaces.
