SimpAb\Simp\Ab is the category of simplicial abelian groups, i.e., of simplicial objects in the category Ab of abelian groups, i.e., it is the functor category of functors from the opposite category Δ op\Delta^{op} of the simplex category Δ\Delta to AbAb:

SimpAb=[Δ op,Ab]. \Simp\Ab = [\Delta^{op}, Ab] \,.
