Let X → Y be a map of unpointed spaces and let Z be a pointed space. Consider factorizations: X f /Y / g Cone(f) {eg Z There is a bijective correspondence {pointed factorizations eg} l {null homotopies gf ’ ∗} Corollary 3.2. Let X → Y be a map of spaces, and let Z be a pointed space. Then the sequence X −→f Y → Cone(f)

WebCoproduct in category of pointed spaces. Let X, Y, Z ∈ T o p ∗ be pointed spaces with basepoints x 0, y 0 and z 0. Then the wedge-sum X ∨ Y = X ⊔ Y / ( x 0 ∼ y 0) is a coproduct of X and Y. Especially given pointed maps f: X → Z and g: Y → Z the map ( f, g) should be continous where. In order to prove continuity let U ⊂ Z be open.
