Titre français : Calcul D'Invariants Primitifs De Groupes Finis
Titre anglais : Calculating Primitive Invariants Of Finite Groups
Abstract : We introduce in this article, a new method to calculate all absolute and relatif primitive invariants of finite groups. This method is inspired from K. Girstmair which calculate an absolute primitive invariant of minimal degree. Are presented two algorithms, the first one enable us to calculate all primitive invariants of minimal degree, and the second algorithm calculate all absolute or relative primitive invariants with distincts coefficients. This work take place in Galois Theory and Invariant Theory.
