✦ Synopsis

APPEAR IN FUTURE ISSUES 499 the anomalous trace of the renormalized vacuum expectation value of the energy-momentum tensor in the case of conformal triviality is discussed. Trace anomaly is shown to be inevitable, if the renormalization recipe is defined in terms of purely geometric quantities, as a consequence of the inexistence of a geometric generalization encompassing every possible space-time of the well-known conformalvacuum at Robertson-Walker universes.
