We introduce theG-sequences which consist of the evaluation subgroups of the homotopy groups in the homotopy sequence of a CW-pair and give some conditions for theG-sequences to be exact. That is, if the inclusioni:A→Xis homotopic to a constant map or has a left homotopy inverse, then theG-sequence of (X,A) is exact. We also show the existence of a nonexactG-sequence and introduce the ω-homology defined by theG-sequence of a CW-pair and the ω-homology of a CW-triple.
