摘要
在Lω-空间中借助βα-ωδ-开覆盖,定义了Lω-空间的相对ωδ-紧性,证明了相对ωδ-紧性被连续的Zadeh型函数所保持,并讨论了其网式刻画。
By means of βα-ωδ-open cover,the notion of relative ωδ-compactness,in L-order-preserving operator spaces is discussed. It is proved that ωδ-compactness is preserved by continuously generalized Zadeh functions and it can also be characterized by nets.
