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。
