  In 1+1 dimensional compact QCD the zero modes of $A^+$ give the theory a non-
trivial topological structure. We examine the effects of these topological
structures on the confining infrared structure of the theory. We show that the
ground state wavefunction of the topological excitation smears the infrared
behavior sufficiently to eliminate confinement for some matter currents. We
review the work of Franke et.al. which shows that the zero modes of$A^+$ in
$QCD_{3+1}$ give rise to instantons. The relation of zero modes of$A^+$.Invited
