Abstract

The aim of this paper is twofold. Firstly, we chatacterize the Besov spaces B˙p,q(Rn,{tk})\dot{B}_{p,q}(\mathbb{R}^{n},\{t_{k}\}) and the Triebel-Lizorkin spaces F˙p,q(Rn,{tk})\dot{F}_{p,q}(\mathbb{R}^{n},\{t_{k}\}) for q=q=\infty . Secondly, under some suitable assumptions on the pp-admissible weight sequence {tk}\{t_{k}\}, we prove that \begin{equation*} \dot{A}_{p,q}(\mathbb{R}^{n},\{t_{k}\})=\dot{A}_{p,q}(\mathbb{R} ^{n},t_{j}),\quad j\in \mathbb{Z}, \end{equation*} in the sense of equivalent quasi-norms, with A˙\dot{A} {B˙,F˙}\in \{\dot{B},\dot{F}\}. Moreover, we find a necessary and sufficient conditions for the coincidence of the spaces A˙p,q(Rn,ti),i{1,2}\dot{A}_{p,q}(\mathbb{R}^{n},t_{i}),i\in \{1,2\}.
