本文研究了预拓扑空间中的收敛问题.利用完备格同构的方法,获得了预拓扑与预收敛类可以相互确定的结果,推广了拓扑与收敛类可以相互确定的结果,同时推广了文献[1]的结果.
In this paper,the problem of convergence in pretopological spaces is studied.By means of complete lattice isomorphism,it is obtained that pretopologies and preconvergence classes on any set can be determined by each other,which generalizes the fact in topological spaces and extends the main theorem in paper[1].
