Journal of Physics A Mathematical and GeneralOn completely positive nonlinear dynamical semigroupsW. A. MajewskiPublished Apr 21, 1990• 9 citationsPublisherAbstractThe general form of infinitesimal generators of completely positive nonlinear semigroups is discussed. It is argued that the condition of complete positiveness is too restrictive.DOI10.1088/0305-4470/23/8/002
