I will extend the notions of Milnor and Tjurina numbers of functions to the framework of Bruce-Roberts numbers, that is, to pairs formed by the germ at 0 of a complex analytic variety X in ℂⁿ and a finitely R(X)-determined analytic function germ f from (ℂⁿ ,0) to (ℂ,0). The aim is to analyze some fundamental properties of these numbers and discuss the relative version of Saito’s theorem. This is a joint work with Carles Bivia-Ausina and Konstantinos Kourliouros.
