... the field of Diophantine equations. The proof uses what may be called the ‘modular’ approach, initiated by Frey ([19], [20]), which has since been applied to many other Diophantine equations; mostly— though ... of papers whereby we combine the classical approach to exponential Diophantine equations (linear forms in logarithms, Thue equations, etc.) with a modular approach based on s...
