We consider the monodromy at infinity and the monodromies around the bifurcation points of polynomial functions $f : \mathbb C^n \longrightarrow \mathbb C$ which are not tame and might have non-isolated singularities. Our ...

Our description of their Jordan blocks in terms of the Newton polyhedra and the motivic Milnor fibers relies on two new issues: the non-atypical eigenvalues of the monodromies and the corresponding concentration results for their generalized eigenspaces.Show less >
