Mixed Bruce–Roberts numbers
We extend the notions of μ*-sequences 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 ⊆ ℂ n and a finitely ${\mathcal R}(X)$ -determined analytic function germ f : (ℂ n , 0) → (ℂ, 0). We analyze som...
