论文摘要
我们调查了$ q $ - manifolds的表征的$ z_n $映射的密度，以及在c（\ mathbb n \ times q，x）$中具有离散图像中的$ l_2 $ manifolds中具有离散图像的映射$ f \的密度可以削弱到同源$ z_n $ z_n $ - $ z的密度。结果，我们获得了$ q $ - manifolds和$ l_2 $ -manifolds的同源特征。
We investigate to what extend the density of $Z_n$-maps in the characterization of $Q$-manifolds, and the density of maps $f\in C(\mathbb N\times Q,X)$ having discrete images in the $l_2$-manifolds characterization can be weakened to the density of homological $Z_n$-maps and homological $Z$-maps, respectively. As a result, we obtain homological characterizations of $Q$-manifolds and $l_2$-manifolds.
