Ta Thi Hoai An, Nguyen Ngoc Diep

摘要:

设$P$和$Q$是特征为零的代数闭域$k$上的一元多项式.设$f$和$g$是$k$上的函数域$\K$的元素,使得$P(f)=Q(g).$,我们给出了关于$P$和$Q$,使得$f$和$g$的高度可以被有效地限制,而且,我们给出了关于$P$和$Q$的充分充分条件,其中$f$和$g$必须为常数。

英文摘要:

Let $P$ and $Q$ be polynomials in one variable over an algebraically closed field $k$ of characteristic zero. Let $f$ and $g$ be elements of a function field $\K$ over $k$ such that $P(f)=Q(g).$ We give conditions on $P$ and $Q$ such that the height of $f$ and $g$ can be effectively bounded, and moreover, we give sufficient conditions on $P$ and $Q$ under which $f$ and $g$ must be constant.
