ANR映射空间的同伦刻画

Homotopy characterization of ANR mapping spaces

Jaka Smrekar

摘要:

设Y是度量空间类的绝对邻域收缩核(ANR),X是T2空间.设映射(X,Y)表示从X到Y的具有紧开拓扑的连续映射空间。证明了若X是CW复形,则映射(X,Y)是度量空间类的ANR当且仅当映射(X,Y)是可度量化的且具有CW复形的同伦型.当X是一个紧生成的半紧空间时,同样成立(在这种情况下,可度量化假设是无效的)。

英文摘要:

Let Y be an absolute neighborhood retract (ANR) for the class of metric spaces and let X be a Hausdorff space. Let map(X,Y) denote the space of continuous maps from X to Y with the compact open topology. It is shown that if X is a CW complex then map(X,Y) is an ANR for the class of metric spaces if and only if map(X,Y) is metrizable and has the homotopy type of a CW complex. The same holds also when X is a compactly generated hemicompact space (metrizability assumption is void in this case).
