Abstract
We prove that for pairwise co-prime numbers there does not exist any infinite set of positive integers such that the representation function becomes constant for large enough. This result is a particular case of our main theorem, which poses a further step towards answering a question of Sárközy and Sós and widely extends a previous result of Cilleruelo and Rué for bivariate linear forms (Bull. of the London Math. Society, 2009).
