The definition of derived set calculation can be obtained according to the closureofset and the characteristics of derived set.
根据导集的性质以及闭包运算的定义,得到导集运算的定义。

Similar to the building of topological Spaces through the calculation of a closureofset, the topological Spaces can also be built through the derived set calculation.
又类似于从闭包运算出发建立拓扑空间,从而得到了从导集运算出发建立的拓扑空间。

The equivalence relation defined by the (transitive closureof the) set of imposed constraints implies N L = N L
