ИСТИНА

One says about the quantum anomaly if after the quantization of the Lagrangian or Hamiltonian system, whose action is invariant with respect to a transformation, one gets a quantum system dynamics of which is not invariant with respect to the same transformation. Recently (2003 and 2006) Oxford University Press and Cambridge University Press published two books in which alternative explanations of the origin of the quantum anomalies were suggested; moreover in the second book it was said that the explanation, given in the first book, is wrong. In the talk a new approach to the analysis of the quantum anomalies will be suggested. It shows that the result of the first book is correct.
