1) semi-generalized open L-set
半广义开L-集
1.
In this paper,we introduce the concepts of semi-generalized closed L-set and semi-generalized open L-set in L-space,and we prove that the union of two semi-generalized closed L-sets is a semi-generalized closed L-set and the image of a sg-closed L-set is a gf-closed L-set in closed and semicontinuous mapping,but in the same mapping the image of sg-open L-set is not gf-open.
引入半广义闭L-集和半广义开L-集,证明两个半广义闭L-集的并也是半广义闭L-集,同样还证明了在闭映射和半连续映射下,sg-闭L-集的像是gf-闭L-集,但是有例子表明,在闭映射和半连续映射下,sg-开L-集的像一般不再是gf-开L-集,此外还证明了闭L-集sg-闭L-集gf-闭L-集rgf-闭L-集,但是每个逆都是不真的。

3) pre-semiopen L-sets
准半开L-集
1.
A new definition of PS-compactness and PS-Lindelf property is presented in L-topological spaces by means of pre-semiopen L-sets and their inequality,where L is a complete DeMorgan algebra.
在L-拓扑空间中借助于准半开L-集及其不等式给出了可数PS-紧性和PS-Lindelf性质的新定义,这里L是完备的DeMorgan代数。
4) Strongly Semi-open L-set
强半开L-集
5) L-fuzzy semi-open sets
L-fuzzy半开集
6) Generalized L-Fuzzy Partial Order Set
广义L-Fuzzy偏序集
