UNIQUENESS THEOREMS IN HOMOLOGY THEORY

Abstract

For suitable sets of axioms, uniqueness theorems are proved in the following categories: a) countable locally finite polyhedra and proper mappings; b) metrizable compacta; c) locally compact second-countable spaces and proper mappings; d) Hausdorff spaces whose compact subspaces are metrizable; e) paracompact weakly locally contractible spaces.Bibliography: 11 items.
