Abstract: Kronecker characterized an algebraic number as being rational by saying that almost all its  mod $p$ reductions are in the prime field $\mathbb{F}_p$. Grothendieck’s $p$-curvature conjecture predicts a similar statement for the solution of linear differential equations. We shall report on the history of the problem and on recent progress.
