Bifurcation values of polynomial functions and perverse sheaves
Takeuchi,Kiyoshi
Annales de l'Institut Fourier      2019   [Refereed]
Ike, Yuichi;Matsui, Yutaka;Takeuchi, Kiyoshi
Int. Math. Res. Not.   (15) 4852-4898   2017
We study Lefschetz fixed point formulas for constructible sheaves with higher-dimensional fixed point sets. Under fairly weak assumptions, we prove that the local contributions from them are expressed by some constructible functions associated to ...

We obtain general upper bounds of the sizes and the numbers of Jordan blocks for the eigenvalues lambda not equal 1 in the monodromies at infinity of polynomial maps.
