We define a morphism of weakly chain U -complexes analog to the definition of morphism of U-complexes, i.e. f : X −→ Y is a morphism of weakly chain U-complexes if f = (fn : Xn −→ Yn)n∈Z is a family of R-modules homomorphisms such that every rectangle commutes and fn ( UXn )	cache/ejpam-3673.pdf	txt/ejpam-3673.txt
