摘要
在弱L-余拓扑空间中引入层紧集概念,并用滤子和网给出层紧性的等价刻画,证明了层紧性在弱连续的L-值Zadeh型函数下是不变的,最后给出链所具有的特征.
The concept of layer-compact set is introduced into the weakly L-cotopology spaces. The concept of layer compactness is defined and characterized in terms of nets and filters. It is shown that the layer-compactness is invariant under the weakly continuous L-valued Zadeh function. The characterization of chains is given.
