Abstract (EN):
In this paper, we prove an extension of Mahler's theorem on interpolation series, a celebrated result of p-adic analysis. Mahler's original result states that a function from N to Z is uniformly continuous for the p-adic metric d(p) if and only if it can be uniformly approximated by polynomial functions. We prove the same result for functions from a free monoid A* to Z. where d(p) is replaced by the pro-p metric, the profinite metric on A* defined by p-groups.
