%X Within the frame of a Group Approach to Quantization anomalies arise in a quite natural way. We present in this talk an analysis of the basic obstructions that can be found when we try to translate
symmetries of the Newton equations to the Quantum Theory.
They fall into two classes: algebraic and topologic according to the local or global character of the obstruction. We present here
one explicit example of each.
