Abstract
In this Note, we refine the notion of motivic Serre invariants. We study the behaviour of these invariants under ramification. We establish a trace formula, which yields a cohomological interpretation of the motivic Serre invariants, in terms of the Lefschetz numbers of the monodromy action on the nearby cycles.
