Description
We study the dual Higgs mechanism for the nonperturbative QCD. We point out two kind of the ``see-saw'' relations between electric and magnetic sectors. Owing to the Dirac condition $eg=4π$, the dual Ginzburg-Landau theory has the asymptotic freedom nature on the gauge coupling constant $e$, where the ``walking coupling constant'' is predicted for $e$ in the infrared region. We study also QCD-monopoles and instantons, which are two relevant topological objects in QCD. Strong correlations between the QCD-monopole trajectory and the topological charge are found both in the continuum theory and in the lattice gauge theory.
