It seems that I have to reformulate the question in the following form: Under the same conditions can one say that $f(x)$ is algebraic over $F(f_1(x),f_2(x),...,f_n(x))$? | |

| May 22, 2015 at 19:19 | comment | added | Felipe Voloch | @DavidHolmes The question makes sense. Maybe it's clearer to ask whether, given the conditions, there is a rational function $g_1$ satisfying the same hypotheses as $g$. | |
| May 22, 2015 at 8:43 | comment | added | David Holmes | Do you mean $g \in F(f_1(x), ... f_n(x))$? Otherwise I don't understand `implies the rationality of $g$'. | |
