Top : Science : Math : Number_Theory : Diophantine_Equations
  • Equal Sums of Like Powers
  • Fermat's Last Theorem

    Sites:
  • Bibliography on Hilbert's Tenth Problem: Searchable, ~400 items.
  • Developing A General 2nd Degree Diophantine Equation x^2 + p = 2^n: Methods to solve these equations.
  • Diagonal Quartic Surfaces: Articles, computations and software in Magma and GP by Martin Bright.
  • Diophantine Geometry in Characteristic p: A survey by José Felipe Voloch.
  • Diophantine m-tuples: Sets with the property that the product of any two distinct elements is one less than a square. Notes and bibliography by Andrej Dujella.
  • Diophantus Quadraticus: On-line Pell Equation solver by Michael Zuker.
  • Egyptian Fractions: Lots of information about Egyptian fractions collected by David Eppstein.
  • Hilbert's Tenth Problem: Statement of the problem in several languages, history of the problem, bibliography and links to related WWW sites.
  • Hilbert's Tenth Problem: Given a Diophantine equation with any number of unknowns and with rational integer coefficients: devise a process, which could determine by a finite number of operations whether the equation is solvable in rational integers.
  • Linear Diophantine Equations: A web tool for solving Diophantine equations of the form ax + by = c.
  • Pell's Equation: Record solutions.
  • Pythagorean Triples Etcetera: A web text by Fred Barnes on 60-, 90-, and 120-degree integer-sided triangles.
  • Pythagorean Triples in JAVA: A JavaScript applet which reads a and gives integer solutions of a^2+b^2 = c^2.
  • Pythagorean Triplets: A Javascript calculator for pythagorean triplets.
  • Quadratic Diophantine Equation Solver: Dario Alpern's Java/JavaScript code that solves Diophantine equations of the form Ax^2 + Bxy + Cy^2 + Dx + Ey + F = 0 in two selectable modes: "solution only" and "step by step" (or "teach") mode. There is also a link to his description of the solving methods.
  • Rational and Integral Points on Higher-dimensional Varieties: Some of conjectures and open problems, compiled at AIM.
  • Rational Triangles: Triangles in the Euclidean plane such that all three sides are rational. With tables of Heronian and Pythagorean triples.
  • Solving General Pell Equations: John Robertson's treatise on how to solve Diophantine equations of the form x^2 - dy^2 = N.
  • The Erdos-Strauss Conjecture: The conjecture states that for any integer n > 1 there are integers a, b, and c with 4/n = 1/a + 1/b + 1/c, a > 0, b > 0, c > 0. The page establishes that the conjecture is true for all integers n, 1 < n <= 10^14. Tables and software by Allan Swett.
  • Thue Equations: Definition of the problem and a list of special cases that have been solved, by Clemens Heuberger.
