Thue Equation
A Thue equation is a Diophantine equation of the form
| A_nx^n+A_(n-1)x^(n-1)y+A_(n-2)x^(n-2)y^2+...+A_0y^n=M |
in terms of an irreducible polynomial of degree n>=3 having coefficients A_i in Z for which solutions in integers x and y are sought for each given constant M in Z with M!=0.
Thue (1909) proved that such an equation has only finitely many solutions, but it was not until much later that Tzanakis and de Weger (1989) gave a practical algorithm for finding bounds on |x| and |y|. Although these bounds can be astronomically large in some cases, they are typically small enough to allow an exhaustive search for all solutions.
