引入并考察了拟一致半连续格,得到了有限个拟一致半连续格的笛卡尔乘积是拟一致半连续格,给出了拟一致半连续格的逆像是拟一致半连续格的一个充分条件。
In its properties. quasi-uniform quasi-uniform this paper, we introduce a concept of quasi-uniform semicontinuous lattice and examine We obtain that the Cartesian product of finite quasi-uniform semicontinuous lattices is a semicontinuous lattice. In addition, we give a sufficient condition for the inverse image of a semicontinuous lattice is a quasi-uniform semicontinuous lattice.
