本文研究了超拓扑的若干性质并得到几个重要结果。
In〔1〕,〔2〕, the some kinds of hypertopologies were introduced for the study of fall-shadow of random sets. The hypertopology Γ22, one of which is studied in this paper. We study some properties of Γ22 and obtain some important results:
( 1 ) Suppose y is subspace of X, then Γ02,(P(X|Y )) is stronger than
Γ02(p(X))|P(Y).
( 2 ) Suppose Y is subspace of X, then Γ22(P(X|Y )) is stronger than Γ22(P(X))|lP(Y).
If Y is a closed subspace of X, then Γ22(P(X|Y )) equivalents Γ22(P(X))|P(Y).
