论文摘要
我们表明，每个可改进的地图都保留了域的共体连接，而近距离改进的地图不一定是。另外，我们证明了共体定性是惠特尼的财产，也不是惠特尼的可逆财产。
We show that each refinable map preserves colocal connectedness of the domain while a proximately refinable map does not necessarily. Also, we prove that colocal connectedness is a Whitney property and is not a Whitney reversible property.
