We study the decidability of the following problem: given p affine functions f 1 ,...,f p over ℕ k and two vectors v 1 ,v 2 ∈ℕ k , is v 2 reachable from v 1 by successive iterations of f 1 ,...,f p (in this given order)? We show that this question is decidable for p=1,2 and undecidable for some fixed p.
