报告题目：Kaplansky Theorem for completely regular spaces

报 告 人：李磊 南开大学副教授

摘 要： Let $X, Y$ be realcompact spaces. Let $\phi$ be a linear bijection from $C(X)$ onto $C(Y)$. We show that if $\phi$ preserves nonvanishing functions, then $\phi$ is a weighted composition operator. This result is applied to other nice function spaces, e.g. uniformly or Lipschitz continuous functions on metric space. This is a joint work with N.-C. Wong.
