| Abstract | For points (a, b) on an algebraic curve over a field K with height h, the asymptotic relation between h(a) and h(b) has been extensively studied in diophantine geometry. When K = k(t) is the field of algebraic functions in t over a field k of characteristic zero, Eremenko in 1998 proved the following quasi-equivalence for an absolute logarithmic height h in K: Given P is an element of K[X, Y] irreducible over K and is an element of > 0, there is a constant C only depending on P and E such that for each (a, b) is an element of K-2 with P (a, b) = 0, (1 - epsilon) deg(P, Y )h(b) - C <= deg(P, X)h(a)<= 1 +epsilon) deg(P, Y )h(b) + C. In this article, we shall give an explicit bound for the constant C in terms of the total degree of P, the height of P and E. This result is expected to have applications in some other areas such as symbolic computation of differential and difference equations. (C) 2022 Elsevier Inc. All rights reserved |
