Resumen
- Galoisian envelope of a rational map. lo 2001, a. Maigrange defines Ibe 21-envelope or galoisian envelope of an analytical dynamical system. Roughly speakiog, tbis is the algebrair boíl of the dynamical system. In this sbort article, the 21-envelope of a rational map R: IP1 -o IP1 is computed. The rational maps characterised by a floitoesí property of their 19-enveiope appear to be the integrable ones.
