Fermat-Catalan Conjecture

Number Theory

The Fermat-Catalan conjecture, in number theory, generalizes both Fermat's Last Theorem and Catalan's conjecture. It states that the equation a to the power m plus b to the power n equals c to the power k, where a, b and c are positive coprime integers and m, n and k are positive integers satisfying one over m plus one over n plus one over k less than 1, has only finitely many solutions with distinct triples of values. The inequality on the exponents is essential, since without it there would be infinitely many solutions.

Facts
Statement
The Fermat-Catalan conjecture, generalizing Fermat's Last Theorem and Catalan's conjecture, states that the equation a to the power m plus b to the power n equals c to the power k, where a, b and c are positive coprime integers and m, n and k are positive integers with one over m plus one over n plus one over k less than 1, has only finitely many solutions with distinct triples a to the m, b to the n, c to the k. 1
Progress Toward Resolution
By the Darmon-Granville theorem, which uses Faltings' theorem, only finitely many coprime solution triples exist for any single fixed choice of exponents m, n and k satisfying the inequality, though the conjecture across all admissible exponent choices remains open; it is known that the abc conjecture would imply the Fermat-Catalan conjecture. 1
