【摘要】 在LΔ-闭包空间中借助于Lα-Δ-开覆盖、α-局部有限集族、α--局部有限集族引入了Δ-仿紧性。证明了它对Δ-闭集是遗传的、Δ-紧的LΔ-闭包空间和Δ-仿紧空间的积空间是Δ-仿紧的重要性质。更多还原

【Abstract】 In this paper a certain Δ-paracompactness is presented by means of the concepts of Lα-Δ-open cover,α-locally finite family and α-locally finite family of L-sets.And we proved that it is inherited by Δ-closed subsets,that the product of a Δ-compactness LΔ-closure spaces and a Δ-paracompact space is Δ-paracompactness.更多还原
