报告摘要：The celebrated Ellis joint continuity theorem says: if $\pi\colon \Gamma\times X\to X$ is a separately continuous phase mapping with $X$ a locally compact Hausdorff phase space and with $\Gamma$ a locally compact Hausdorff semi-topological group, then $\pi$ is jointly continuous. We will give some notes to Ellis theorem.
