Our aim in this paper is to prove the general mod C suspension theorem: Suppose that X and Y are CW-complexes,C is a class offinite abelian groups, and that(i) πi(Y) ∈Cfor all i < n,(ii) H*(X; Z) is finitely generated,(iii) Hi(X;Z) ∈Cfor all i > k. Then the suspension homomorphism is a(mod C) monomorphism for 2 ≦ r ≦ 2n – k – 2 (when r= 1, ker E is a finite group of order d, where Zd ∈ C and is a (mod C) epimorphism for 2 ≦ r ≦ 2n – k – 2The proof is basically the same as the proof of the regular suspension theorem. It depends essentially on (mod C) versions of the Serre exact sequence and of the Whitehead theorem.
