| Abstract: | Galoisian envelope of a rational map. In 2001, B. Malgrange defines the D-envelope or galoisian envelope of an analytical dynamical system. Roughly speaking, this is the algebraic hull of the dynamical system. In this short article, the D-envelope of a rational map R: P 1 → P 1 is computed. The rational maps characterised by a finitness property of their D-envelope appear to be the integrable ones. |
