Yang-Mills Theory for Noncommutative Flows Addendum
  This supplementary manuscript is to describe an important nontrivial example, which appears in the matrix model of type IIB in the super string theory in order to apply a new duality for the moduli spaces of Yang-Mills connections on noncommutative vector bundles. Actually, the moduli space of the instanton bundle over noncommutative Euclidean 4-spaces with respect to the canonical action of space translations is computed precisely without using the ADHM- construction.
