Thue's theorem

Thue's theorem

:"You might be looking for" Thue–Siegel–Roth theorem.

Thue's theorem is a mathematical theorem first proved by Axel Thue in 1909. [A. Thue, "Über Annäherungswerte algebraischer Zahlen", Journal für die reine und angewandte Mathematik, 135, pages 284-305 (1909)]

It also refers to the 2-dimensional analog of Kepler's conjecture: the regular hexagonal packing is the densest sphere packing in the plane (1890).

tatement of Thue's theorem

If "f" is a bivariate form with rational coefficients which is irreducible over the rational numbers and has degree greater than or equal to 3, and r is a rational number other than 0, then the equation:"f"("x","y")="r"has only finitely many solutions in integers "x" and "y".

An equation of the form "f"("x","y")="r", where "f" and "r" are as in the theorem, is called a Thue equation. Hence the theorem can be stated concisely as: Any Thue equation has only finitely many integer solutions.
