Main two ingredients of the definition are equivariant Lefschetz numbers and the λ-structure on the Grothendieck ring of finite G-sets. We give an A’Campo type formula for the equivariant zeta function.engjournal articlehttp://www.ams.org/bookstore/trans2seriesopen access512.7Monodromy zeta functionEquivariant Lefschetz numberGrothendieck ringGeometria algebraica1201.01 Geometría Algebraica
