作者姓名:郑崇友  楊安洲
摘    要:Let X be an infinite set, K={τ:τ is a topology on X}, C={τ:τ∈K&τ is acomplete lattice of sets with respect to operations of arbitrary intersection andunion}. Theorem 1 For a given τ∈K, we define (τ)={σ:σ∈K & σo and τ are homeomorphic}, then sup{|<τ>):τ∈K}=max{|<τ>|:τ∈K}=2~|X|=exp(|X|).
