Abstract

Let p be a prime number. For a positive integer n and a p -adic number ξ , let λ n ( ξ ) denote the supremum of the real numbers λ such that there are arbitrarily large positive integers q such that qξ p , qξ 2 p ,..., qξ n p are all less than q − λ − 1 . Here, x p denotes the infimum of | x − n | p as n runs through the integers. We study the set of values taken by the function λ n
