On Hopf anomaly

This is a very brief but selfcontained review of the concept of quantum group symmetries and their anomalies. Remarkably, general constructions can be very simply illustrated on the standard harmonic oscillator which is shown to possess a non-commutative and non-cocommutative anomalous quantum group symmetry.
