原始语种摘要: Let $ \varphi $ be an analytic self-map of the open unit disk $ \mathbb{D}$. We study the complex symmetry of composition operators $ C_\varphi $ on weighted Hardy spaces induced by a bounded sequence. For any analytic self-map of $ \mathbb{D}$ that is not an elliptic automorphism, we establish that if $ C_{\varphi }$ is complex symmetric, then either $ \varphi (0)=0$ or $ \varphi $ is linear. In the case of weighted Bergman spaces $ A^{2}_{\alpha }$, we find the non-automorphic linear fractional symbols $ \varphi $ such that $ C_{\varphi }$ is complex symmetric.
