Abstract: A weighted composition operator $ C_{\psi,\varphi}$ takes an analytic map $ f$ on the open unit disk of the complex plane to the analytic map $ \psi f\circ \varphi$, where $ \varphi$ is an analytic map of the open unit disk into itself and $ \psi$ is an analytic map on the open unit disk. This paper studies how the compactness of $ C_{\psi,\varphi}$ depends on the interaction between the two maps $ \psi$ and $ \varphi$.
