The first one defines it as an element of the Burnside ring of the group. The second approach emerged from physics and includes the orbifold Euler characteristic and its higher order versions. Here we give a way to merge the two approaches together defining (in a certain setting) higher order Euler characteristics with values in the Burnside ring of a group. We give Macdonald type equations for these invariants. We also offer generalized (“motivic”) versions of these invariants and formulate Macdonald type equations for them as well.engjournal articlehttp://www.mathjournals.org/mmj/2016-016-004/2016-016-004-010.htmlhttp://www.mathjournals.orgopen access517.5Finite group actionsOrbifold Euler characteristicBurnside ringComplex quasi-projective varietiesWreath productsGenerating series.Funciones (Matemáticas)1202 Análisis y Análisis Funcional
