Monodromy zeta functions at infinity, Newton polyhedra and constructible sheaves

Yutaka Matsui, Kiyoshi Takeuchi

Published 2008-09-18, updated 2009-12-28Version 10

By using sheaf-theoretical methods such as constructible sheaves, we generalize the formula of Libgober-Sperber concerning the zeta functions of monodromy at infinity of polynomial maps into various directions. In particular, some formulas for the zeta functions of global monodromy along the fibers of bifurcation points of polynomial maps will be obtained.
