摘要
在qw*闭拓扑的基础上提出了Q(Qr)空间的概念,给出了一重要结论:连续线性算子u将局部凸分离空间X的包囿桶映为局部凸分离空间Y中的包囿集,则共轭算子u′保持qw*闭集,进而若X是Q空间,则Y也是Q空间.
In this paper,the notions of Q(Qr) Spaces are introduced based on qw* closed topology and we draw important conclusions: let X,Y be lcs spaces,and u:X → Y a continuous linear operator,A bornological barrel in X,u(A),bornological set,then the dual operator u′of u preserves qw* closed sets,further if X is Q space,then Y is also Q space.
