Arithmetical Congruence Preservation: from Finite to Infinite

Patrick Cégielski, Serge Grigorieff, Irène Guessarian

Various problems on integers lead to the class of congruence preserving functions on rings, i.e. functions verifying $a - b$ divides $f (a) - f (b)$ for all $a, b$ . We characterized these…

Characterizing congruence preserving functions $Z / n Z \to Z / m Z$ via rational polynomials

Patrick Cegielski, Serge Grigorieff, Irene Guessarian

We introduce a basis of rational polynomial-like functions $P_{0}, \dots, P_{n - 1}$ for the free module of functions $Z / n Z \to Z / m Z$ . We then characterize the subfamily of congruence pr…
