Résumé : In this talk I'll outline an application of differential invariants to algebraic problems. The proposed approach is based on a version of Lie-Tresse theorem proven by Kruglikov-Lychagin. This method will be illustrated on the classical classification problems for Lie group actions on n-ary forms. The last part of the talk is based on joint results with Pavel Bibikov.
