Home›Number Theory›Diophantine Equations›All Diophantine EquationsBrowse ByAll Diophantine EquationsThis group gathers theorems about integer and rational solutions to polynomial equations, the oldest and broadest branch of number theory, together with the closely related theory of how well irrational numbers can be approximated by fractions. It includes landmark equations such as Fermat's Last Theorem, Pell's equation, and the Catalan and Ramanujan-Nagell equations, the classical technique of infinite descent used to rule out solutions, and the approximation results of Liouville, Thue, Roth, and Schmidt that grew out of the same questions about how closely a number can be pinned down by rationals.FactsAll Diophantine EquationsSourcesComments (0)Reader Challenges (0)FactsComparisonEra Of EmergenceWell-attested250 1All Diophantine EquationsFilter Results30 entriesBranchAllAlgebraic Geometry (1)Algebraic Number Theory (1)Geometry (1)Number Theory (24)Topic AreaAllDiophantine Equations (30)ProvedAll1737 (1)1768 (1)1823 (1)1844 (1)1884 (1)1909 (1)1929 (1)1935 (1)1944 (1)1946 (1)1948 (2)1955 (1)1964 (1)1972 (1)1976 (1)1978 (1)1994 (1)1995 (1)2002 (1)Proved ByAllAndrew Wiles (3)Carl Ludwig Siegel (2)Charles Hermite (1)Claude Chevalley (1)Joseph Liouville (1)Joseph-Louis Lagrange (1)Kurt Mahler (2)Leonhard Euler (2)Leopold Kronecker (1)Peter Gustav Lejeune Dirichlet (1)Pierre de Fermat (1)Preda Mihăilescu (1)Robert Tijdeman (1)Sophie Germain (1)Srinivasa Ramanujan (1)Stanisław Świerczkowski (1)Thoralf Skolem (1)Vera T.
