The abc-inequality and the generalized Fermat equation in function fields
We show that the Diophantine equation of the title has, for , no solution in coprime nonzero integers and . Our proof relies upon Frey curves and related results on the modularity of Galois representations.
Each of the Diophantine equations has an infinite number of integral solutions for any positive integer . In this paper, we will show how the method of infinite ascent could be applied to generate these solutions. We will investigate the conditions when , and are pair-wise co-prime. As a side result of this investigation, we will show a method of generating an infinite number of co-prime integral solutions of the Diophantine equation for any co-prime integer pair .
