Product formula of epsilon factors for l-adic sheaves, proven by Laumon, is one of the key points in the Lafforgue's proof of Langlands correspondence for function fields, in the sense that the formula makes possible to argue by the induction on the rank. In my talk, I'd like to talk about my result with A. Marmora on an analogue of this formula in the context of p-adic cohomology.
