摘要：

We compute finite-volume corrections to nucleon matrix elements of the axial-vector current. We show that knowledge of this finite-volume dependence-as well as that of the nucleon mass-obtained using lattice QCD may allow a clean determination of the chiral-limit values of the nucleon and Delta-resonance axial-vector couplings.
