Query: Trace anomaly and infrared cutoffs   The Effective Average Action is a form of effective action which depends on a
cutoff scale suppressing the contribution of low momentum modes in the
functional integral. It reduces to the ordinary effective action when the
cutoff scale goes to zero. We derive the modifications of the scale Ward
identity due to this cutoff and show how the resulting identity then intimately
relates the trace anomaly to the Wilsonian realisation of the renormalization
group.
