发展了有限性阻塞和简单同伦理论“在ε overX内”的版本。这提供了一个设置障碍的地图类似物的结束和s-协边定理的流形。这些被应用到研究等变映射圆柱邻域的拓扑群作用,三角剖分的局部三角空间,和块丛结构的近似纤维。
Versions of the finiteness obstruction and simple homotopy theory “within ε overX” are developed. This provides a setting for obstructions to the map analogs of the end ands-cobordism theorems for manifolds. These are applied to study equivariant mapping cylinder neighborhoods in topological group actions, triangulations of locally triangulable spaces, and block bundle structures on approximate fibrations.
