摘要:Let n and m be infinite cardinals with n≤m and n be a regular cardinal. We prove
certain implications of [n,m]-strongly paracompact, [n,m]-paracompact and [n,m]-metacompact
spaces. Let X be [n,∞]-compact and Y be a [n,m]-paracompact (resp. [n,∞]-paracompact), Pn-space
(resp. wPn-space). If m=∑k<nmk we prove that X×Y is [n,m]-paracompact (resp. [n,∞]-paracompact
