Title: Local root numbers for Heisenberg representations

Abstract:

On the Langlands program, explicit computation of the local root numbers

(or epsilon factors) for Galois representations is an integral part.

But for arbitrary Galois representation of higher dimension, we do not

have explicit formula for local root numbers. In our recent work

(joint with Ernst-Wilhelm Zink) we consider Heisenberg representation

(i.e., it represents commutators by scalar matrices) of the Weil
