Section 1: General expression of an algebraic function: Part 11
Translated by me as:
From all the forgoing we conclude:
If v is an algebraic function of order μ and degree m, we can always pose:
v = q0 + p 1 / n + q2 . p 2 / n + ... q n-1. p ( n-1) / n ;
where n is a prime number, q0, q2 ... q n-1 are algebraic functions of order μ and degree m - 1 and also, p is an algebraic function of order μ - 1 and p 1 / n cannot be expressed as a rational function of q0, q2 ... q n-1. [original text corrected]
Commentary:
This is just a restatement of what has been established up to this point. There is a misprint where q1 should be replaced by q2. Abel does not mention it but p is of unrestricted degree.
