Motivic infinite cyclic covers

Anatoly Libgober (University of Illinois at Chicago)


I will describe contruction of invariant of infinite cyclic covers taking values in the Grothendieck group of complex algebraic varieties. This will generalize Denef-Loeser motivic Milnor fiber as well as other versions of motivic Milnor fibers which appeared recently (joint work with M. Gonzalez-Villa and L. Maxim).
