摘要:
We define Abel arithmetic functions in function fields with positive characteristic. We prove that any Abel arithmetic function with exponential type lesser than 1/e ln q is a polynomial, the bound 1/e ln q being optimal. This provides an analog of a Bertrandias' result. Some q-analogs are considered too.
