For a map p : X → A, there are concepts of co-H p -spaces, co-T p -spaces, which are generalized ones of co-H-spaces [17,18]. For a principal cofibration i r : X → C r induced by r : X ′ → X from ι : X ′ → cX ′ , we obtain some sufficient conditions to having extensions co-H p¯ -structures and co-T p¯ -structures on C r of co-H p -structures and co-T p -structures on X respectively. We can also obtain some results about co-H p -spaces and co-T p -spaces in homology decompositions for spaces, which are generalizations of Golasinski and Klein’s result about co-H-spaces.
