Abstract
We study the problem of removing an element from an additive basis in a general abelian group. We introduce analogues of the classical functions X, S and E (defined in the case of ℕ) and obtain bounds on them. Our estimates on the functions S G and E G are valid for general abelian groups G while in the case of X G we show that distinct types of behaviours may occur depending on G.
