摘要
The main interests here are to study the relationship between card(X)and card(P(X))and the connection between the separability of a space X and cardinality of some function space on it.We will convert the calculation of card(P(X))to the calculation of card(F(X!Q)).The main tool we used here is Zorn Lemma.
