Abstract:
For a pointed compactum (X, x), a natural homomorphism ${\xi _n}$ from the Quigley’s approaching group ${\underline {\underline \pi } _n}(X,x)$ to the Steenrod homology group $^s{H_{n + 1}}(X)$ is defined. A shape theoretical condition under which ${\xi _n}$ is an isomorphism is obtained. For every pointed ${S^n}$-like continuum (X, x), ${\xi _n}$ is an isomorphism for $n \ne 2$ and ${\xi _2}$ is an isomorphism if and only if X is movable.References
