Differential algebra and generalizations of Grothendieck's conjecture on the arithmetic of linear differential equations
Abstract: Influenced by work of Chatzidakis-Hrushovski asnd using results of Bost, we show that the Grothendieck-
Katz conjecture is equivalent to a certain nonlinear generalization (introduced by Ekedahl et al) modulo a
differential-algebraic statement concerning "nonorthogonality to the constants".
