Extending work of Bell and of Bell, Ghioca, and Tucker, we prove that for a p-adic analytic self-map f on a closed unit polydisk, if every coefficient of f ( x ) − x has valuation greater than that of p 1 / ( p − 1 ) , then the iterates of f can be p-adically interpolated; that is, there exists a function g ( x , n ) analytic in both x and n such that g ( x , n ) = f n ( x ) whenever n ∈ Z ⩾ 0 .
