Gerd Faltings (; born 28 July 1954) is a German mathematician known for his work in arithmetic geometry. He was awarded the Fields Medal in 1986 for his proofs of the Mordell conjecture and several related conjectures. He won the Abel Prize in 2026 for these achievements.
Faltings was born on July 28th 1954 in Gelsenkirchen-Buer, West Germany. From 1972 to 1978, Faltings studied mathematics and physics at the University of Münster. Interrupted by 15 months of obligatory military service, he received his Dr. rer. nat. in mathematics in 1978.
In 1981, he obtained the venia legendi (Habilitation) in mathematics from the University of Münster. During this time, he was an assistant professor at the University of Münster. From 1982 to 1984, he was a professor at the University of Wuppertal.
From 1985 to 1994, he was a professor at Princeton University. In the autumn of 1988 and in the academic year 1992âÂÂ1993, he was a visiting scholar at the Institute for Advanced Study.
He was awarded the Fields Medal in 1986 for proving the Tate conjecture for Abelian varieties over number fields, the Shafarevich conjecture for Abelian varieties over number fields and the Mordell conjecture, which states that any non-singular projective curve of genus g > 1 defined over a number field K contains only finitely many K-rational points.
In 1994, as an invited speaker at the International Congress of Mathematicians he gave a talk (). Extending methods of Paul Vojta, he proved the MordellâÂÂLang conjecture, which is a generalization of the Mordell conjecture. Together with Gisbert Wüstholz, he re-proved Roth's theorem, for which Roth had been awarded the Fields medal in 1958.
He returned to Germany the same year, and from 1994 to 2018, he was a director of the Max Planck Institute for Mathematics in Bonn. In 1996, he received the Gottfried Wilhelm Leibniz Prize of the Deutsche Forschungsgemeinschaft.
Faltings has been the formal supervisor of over a dozen PhD students, including Shinichi Mochizuki, Wiesà Âawa Nizioà Â, and Nikolai Durov.
On 19 March 2026, the Norwegian Academy of Science and Letters announced Faltings as the winner of the Abel Prize, "for introducing powerful tools in arithmetic geometry and resolving long-standing diophantine conjectures of Mordell and Lang." He is the first German mathematician to have received both the Fields Medal and the Abel Prize.
Faltings married Angelika Tschimmel in 1984; she died in 2011.
