拓扑极限 [tuò pū jí xiàn]
topological limit
- 文摘:给出了极限空间、完备格、拓扑空间、以及L-拓扑空间相互关系的一简要缩述.
Abstract: In this paper, we give a brief survey to some basic results on the interrelationship between limit spaces, complete lattices, topological spaces, and L-topological spaces. - 摘要讨论圆周上一类比扩张映射更广泛的连续映射，证明这种映射是拓扑稳定的，幷且其逆极限系统是可扩的。
The present paper shows that a class of continuous maps on circles which is extensiver than expand maps is topological stable. And its inverse limit systems are expansive. - 利用关于Ⅰ类二次系统的已知结果,在此文中我们系统分析了Ⅲ类二次系统当α=0时其极限环的产生与消失的整个过程,并给出了一些新的拓扑结构变化,它们在Ⅰ类系统中是不会出现的.
By using the known results of type Ⅰ quadratic system, we analyse thecreation and disappearance of limit cycles for type Ⅲ system as a = 0, and obtainsome new topological structures of phase-portraits, which do not appear for type Ⅰsystem.
