摘要
Let P be a family of primes and Z<sub>（p）</sub> the integers localized at P. A pointed connected CW-complex X is said to be homotopy P-local if the homotopy groups π<sub>n</sub>X for all n≥1 are Z<sub>（p）</sub>-modules, and homology P-local if the homology groups H<sub>n</sub>X for all n≥1 are Z<sub>（p）</sub>-modules.
