CHARACTERIZATIONS OF BESOV SPACES IN THE UNIT BALL
Li, Songxiao Korean Mathematical Society 2012 대한수학회보 Vol.49 No.1
In this paper we obtain some new characterizations of Besov spaces on the unit ball of $\mathbb{C}^n$. These characterizations are also completely new even in the settings of the unit disk.

A NOTE OF WEIGHTED COMPOSITION OPERATORS ON BLOCH-TYPE SPACES
LI, SONGXIAO,ZHOU, JIZHEN Korean Mathematical Society 2015 대한수학회보 Vol.52 No.5
We obtain a new criterion for the boundedness and compactness of the weighted composition operators ${\psi}C_{\varphi}$ from ${\ss}^{{\alpha}}$(0 < ${\alpha}$ < 1) to ${\ss}^{{\beta}}$ in terms of the sequence $\{{\psi}{\varphi}^n\}$. An estimate for the essential norm of ${\psi}C_{\varphi}$ is also given.

We obtain a new criterion for the boundedness and compactness of the weighted composition operators ψCφ from Bα(0 < α < 1) to Bβ in terms of the sequence {ψφn}. An estimate for the essential norm of ψCφ is also given.
WEIGHTED COMPOSITION OPERATORS FROM BERGMAN SPACES INTO WEIGHTED BLOCH SPACES
LI SONGXIAO Korean Mathematical Society 2005 대한수학회논문집 Vol.20 No.1
In this paper we study bounded and compact weighted composition operator, induced by a fixed analytic function and an analytic self-map of the open unit disk, from Bergman space into weighted Bloch space. As a corollary, obtain the characterization of composition operator from Bergman space into weighted Bloch space.
MULTIPLIERS OF DIRICHLET-TYPE SUBSPACES OF BLOCH SPACE
Li, Songxiao,Lou, Zengjian,Shen, Conghui Korean Mathematical Society 2020 대한수학회보 Vol.57 No.2
Let M(X, Y) denote the space of multipliers from X to Y, where X and Y are analytic function spaces. As we known, for Dirichlet-type spaces 𝓓<sub>α</sub><sup>p</sup>, M(𝓓<sub>p-1</sub><sup>p</sup>, 𝓓<sub>q-1</sub><sup>q</sup>) = {0}, if p ≠ q, 0 < p, q < ∞. If 0 < p, q < ∞, p ≠ q, 0 < s < 1 such that p + s, q + s > 1, then M(𝓓<sub>p-2+s</sub><sup>p</sup>, 𝓓<sub>q-2+s</sub><sup>q</sup>) = {0}. However, X ∩ 𝓓<sub>p-1</sub><sup>p</sup> ⊆ X ∩ 𝓓<sub>q-1</sub><sup>q</sup> and X ∩ 𝓓<sub>p-2+s</sub><sup>p</sup> ⊆ X ∩ 𝓓<sub>q-2+s</sub><sup>p</sup> whenever X is a subspace of the Bloch space 𝓑 and 0 < p ≤ q < ∞. This says that the set of multipliers M(X ∩ 𝓓 <sub>p-2+s</sub><sup>p</sup>, X∩𝓓<sub>q-2+s</sub><sup>q</sup>) is nontrivial. In this paper, we study the multipliers M(X ∩ 𝓓<sub>p-2+s</sub><sup>p</sup>, X ∩ 𝓓<sub>q-2+s</sub><sup>q</sup>) for distinct classical subspaces X of the Bloch space 𝓑, where X = 𝓑, BMOA or 𝓗<sup>∞</sup>.

Multipliers of Dirichlet-type subspaces of Bloch space
Songxiao Li,Zengjian Lou,Conghui Shen 대한수학회 2020 대한수학회보 Vol.57 No.2
Let $M(X,Y)$ denote the space of multipliers from $X$ to $Y,$ where $X$ and $Y$ are analytic function spaces. As we known, for Dirichlet-type spaces $\mathcal{D}_{\alpha}^p,$ $M(\mathcal{D}^p_{p-1},\mathcal{D}^q_{q-1})=\{0\},$ if $p\neq q,$ $0<p,q<\infty.$ If $0<p,q<\infty,$ $p\neq q,$ $0<s<1$ such that $p+s,q+s>1,$ then $M(\mathcal{D}^p_{p-2+s},\mathcal{D}^q_{q-2+s})=\{0\}.$ However, $X\cap\mathcal{D}^p_{p-1} \subseteq X\cap\mathcal{D}^q_{q-1}$ and $X\cap \mathcal{D}^p_{p-2+s} \subseteq X\cap \mathcal{D}^q_{q-2+s}$ whenever $X$ is a subspace of the Bloch space $\mathcal{B}$ and $0<p\leq q<\infty.$ This says that the set of multipliers $M(X\cap \mathcal{D}^p_{p-2+s},X\cap\mathcal{D}^q_{q-2+s})$ is nontrivial. In this paper, we study the multipliers $M(X\cap\mathcal{D}^p_{p-2+s},X\cap\mathcal{D}^q_{q-2+s})$ for distinct classical subspaces $X$ of the Bloch space $\mathcal{B},$ where $X=\mathcal{B},$ $BMOA$ or $\H^{\infty}.$
