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), P_n-space (resp. wP_n-space). If (The equation is abbreviated) we prove that X×Y is [n,m]-paracompact (resp.[n,∞]-paracompact)
