    Abstract

    In this article we present exact calculations that substantiate a clear picture relating the confining force of QCD to the zero-modes of the Faddeev-Popov (FP) operator M(gA)=-∂·D(gA). This is done in two steps. First we calculate the spectral decomposition of the FP operator and show that the ghost propagator G(k;gA)=k→|M-1(gA)|k→
