Abstract. Suppose $\varphi$ is an analytic self map of $\mathbb{B}_n$ and $\psi$ is analytic on $\mathbb{B}_n$. Then a weighted composition operator induced by $\varphi$ with weight $\psi$ is given by $\left(W_{\psi, \varphi}f\right)\left(z\right) = \psi(z) f(\varphi(z))$ for $z$ in $\mathbb{B}_n$ and f analytic on $\mathbb{B}_n$. Given $W_{\psi, \varphi} : A^{p}_{\alpha}(\mathbb{B}_{n}) \rightarrow A^{q}_{\beta}(\mathbb{B}_{n})$ we characterize boundedness and compactness of $W_{\psi, \varphi}$, where $0<p, q<\infty$ and $-1<\alpha, \beta<\infty$. We also characterize the Schatten $p$-class weighted composition operators $S_{p}\left(A^{2}_{\alpha}(\mathbb{B}_{n})\right)$ for $0<p<\infty$ and $-1<\alpha<\infty$.
