**Gauss congruences for rational functions in several variables**

Frits Beukers, Marc Houben, Armin Straub — Preprint — 2017

## Abstract

We investigate necessary as well as sufficient conditions under which the Laurent series coefficients \(f_{\boldsymbol{n}}\) associated to a multivariate rational function satisfy Gauss congruences, that is \(f_{\boldsymbol{m}p^r} \equiv f_{\boldsymbol{m}p^{r-1}}\) modulo \(p^r\). For instance, we show that these congruences hold for certain determinants of logarithmic derivatives. As an application, we completely classify rational functions \(P/Q\) satisfying the Gauss congruences in the case that \(Q\) is linear in each variable.## Download
