报告摘要:  In this talk, we show some sufficient conditions for maps between groups of positive continuous functions to be composition operators. Moreover, we also show some approximate results on composition operators between continuous function spaces. In particular, we show some optimal approximations for surjective and non-surjective composition operators between uniform algebras.
