%0 Journal Article %A Melle Hernández, Alejandro %A Gusein-Zade, Sabir Medgidovich %A Luengo Velasco, Ignacio %T An equivariant version of the monodromy zeta function %D 2008 %@ 0065-9290 %U https://hdl.handle.net/20.500.14352/49731 %X We offer an equivariant version of the classical monodromy zeta function of a singularity as a series with coefficients from the Grothendieck ring of finite G-sets tensored by the field of rational numbers. 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. %~
