Abstract

In this paper we completely solve a simple quartic family of Thue equations over C(T)\mathbb{C}(T). Specifically, we apply the ABC-Theorem to find all solutions (x,y)C[T]×C[T](x,y) \in \mathbb{C}[T] \times \mathbb{C}[T] to the set of Thue equations Fλ(X,Y)=ξF_{\lambda}(X,Y) = \xi, where ξC×\xi \in \mathbb{C}^{\times} and \begin{equation*} F_{\lambda}(X,Y):=X^4 -\lambda X^3Y -6 X^2Y^2 + \lambda XY^3 +Y^4, \quad \quad \lambda \in \mathbb{C}[T]/\{\mathbb{C}\} \end{equation*} denotes a family of quartic simple forms.
