2) semi-generalized closed L-set
半广义闭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) weak semi-open (closed) set
弱半开(闭)集
1.
Some connections between the weak semi-open (closed) set and the semi-open (closed), the weak semi-interior (closure) and the semi-interior (closure) are investigated.
定义了L-fuzzy子空间中的弱半开(闭)集、弱半内部、弱半闭包等概念,研究L-fuzzy子空间中的弱半开(闭)集与全空间中的半开(闭)集、弱半内部与半内部、弱半闭包与半闭包之间的关系,利用取补、取弱半内部和弱半闭包运算使Kuratowski’s十四集定理在L-fuzzy子空间中得到一般化。
