In this work we compared the predictions of QT for vanishing with the predictions of NM. Generally, the predictions of a physical theory are a logical consequence of (a) the mathematical form of its basic equations, and (b) the set of initial values. Both aspects have been studied in this work, in order to take into account all possible ways to create predictions of NM from QT in the limit . This comparison has been performed for the simplest and most significant situation of single particles in external potentials. Our conclusion is that NM cannot be identified with the limit of QT. This mathematical result should be taken into account in considerations about the interpretation of QT.
