Sažetak
A triad (X, A, B) of topological spaces consists of a topological space X and two subspaces A and B such that A∪B=X. If A and B are closed subsets of X, and if A, B, A∩B and X are ANRs, then (X, A, B) is called an ANR-triad. In the paper being reviewed, an ANR-resolution is defined and it is shown that all triads have ANR-resolutions. An excision theorem, for the Steenrod-Sitnikov homology for arbitrary spaces, follows from the results of this paper [see Yu. Lisitsaand the author, Topology Appl. 20 (1985), no. 1, 29–39].
