From tracial anomalies to anomalies in Quantum Field Theory

Alexander Cardona, Catherine Ducourtioux, Sylvie Paycha

zeta-regularized traces, resp. super-traces, are defined on a classical pseudo-differential operator A by: tr^Q(A):= f.p.tr(A Q^{-z})_{|_{z=0}}, resp. str^Q(A):= f.p.str(A Q^{-z})_…
