The notion of base-countably paracompact space is introduced and some of its equivalent characterizations are obtained:(i)X is a base-countably paracompact space if there exsists an open basis B for X with |B|=ω(X) such that every countably open cover U={Ui}i∈N of X has a locally finite countabe refinement B′ by members of B,B′={Bi}i∈N and BiUi.
引入了基-可数仿紧空间的概念,给出基-可数仿紧空间的一些等价刻画,获得以下结果:(i)X是基-可数仿紧空间当且仅当存在X的一开基B,|B|=ω(X),对于X的每一可数开覆盖U={Ui}i∈N,都存在B′B,使得B′={Bi}i∈N是U的局部有限的可数开加细,且BiUi;(ii)设X是正规空间,X是基-可数仿紧空间当且仅当存在的一开基B,|B|=ω(X),使得X的每一可数开覆盖都存在由B中的元构成的局部有限的收缩。

locally finite group
局部有限群【】叨uy五‘teg心甲;.Ka月研。幼邢，翻rPynna] 每一有限生成子群皆有限的群.任意局部有限群是一个扭群(见周期群(详石浏c脚uP))，但反之未必成立(见R川亩山问题(Burnside prob七m)).一个局部有限群被另一局部有限群的扩张仍是局部有限群.满足子群(甚至是Abel子群)的极小条件的每个局部有限群均包含一个指数有限的Abel子群(【3」)(见具有有限性条件的群(gro叩俪tha血址n郎co画-tion)).一个其Abel子群具有有限秩(见群的秩(扭瓜of ag心tlP))的局部有限群本身亦具有有限秩，且包含一个有限指数的局部可解子群(见局部可解群(1.llysol姐ble grouP)).
