A Note on Integrability and Internality in DCF0

Submission date: 20 December 2012.


We investigate the relationship between algebraic integrability and the model theoretic notion of internality. Our main result give a geometric account of almost internality and indeed we show that this notion correspond in a reasonable way to having enough “good” first integrals.
