Abstract : We obtain a new criterion for the boundedness and compactness of the weighted composition operators $\psi C_\varphi$ from $\B^\alpha(0<\alpha<1)$ to $\B^\beta$ in terms of the sequence $\{\psi\varphi^n\}$. An estimate for the essential norm of $\psi C_\varphi$ is also given.
Keywords : weighted composition operator, Bloch-type space, essential norm
