AbstractLetK be an algebraic number field,S⊇S\t8 a finite set of valuations andC a non-singular algebraic curve overK. Letx∈K(C) be non-constant. A pointP∈C(K) isS-integral if it is not a pole ofx and |x(P)|v>1 impliesv∈S. It is proved that allS-integral points can be effectively determined if the pair (C, x) satisfies certain conditions. In particular, this is the case if(i)x:C→P1 is a Galois covering andg(C)≥1;(ii)the integral closure of
$$\bar Q$$
[x] in
$$\bar Q$$
(C) has at least two units multiplicatively independent mod
$$\bar Q$$
*.
This generalizes famous results of A. Baker and other authors on the effective solution of Diophantine equations.
