Concordance and isotopy of metrics with positive scalar curvature, II
  In this article, the author provides full details of the proof of the concordance/isotopy problem. The first published proof,   [5], accomplished this task only partially since there was an error, see the erratum [6], which damaged the main argument of   [5, Theorem 2.9], and, consequently, the proof of [5, Theorem A].
