On the Functors Cwa and Pa


suspensions of A and attaching cones on suspensions of A (see [5, corollary 3.7]). If A = S, then a relative S–CW–complex is essentially an ordinary relative CW– complex. Any pointed map f : X → Y can be factored as a composition (X → Y ′ p → Y ), where (Y ′, X) is a relative A–CW–complex and p induces a weak equivalence of mapping spaces p? : map?(A, Y… (More)
