%0 Journal Article %T Analytic version of critical $Q$ spaces and their properties %A Pengtao Li %A Junming Liu %A Zengjian Lou %J Mathematics %D 2014 %I arXiv %X In this paper, we establish an analytic version of critical spaces $Q_{\alpha}^{\beta}(\mathbb{R}^{n})$ on unit disc $\mathbb{D}$, denoted by $Q^{\beta}_{p}(\mathbb{D})$. Further we prove a relation between $Q^{\beta}_{p}(\mathbb{D})$ and Morrey spaces. By the boundedness of two integral operators, we give the multiplier spaces of $Q^{\beta}_{p}(\mathbb{D})$. %U http://arxiv.org/abs/1406.1299v1
