Wiles announced this result in the summer of 1993; however, there was a gap in his work. The paper of Taylor and Wiles does not close this gap but circumvents it. This article by Faltings [1983] (which asserts that a curve of genus greater than 1 de ned over a number eld has only a nite number of points rational over that number eld). As an example of an application of this theorem, choose your favorite polynomial g(x) with rational coe cients, no multiple roots, and of degree 5, for example g(x) = x(x 1)(x 2)(x 3)(x 4); In mathematics, the Mordell–Weil theorem states that for an abelian variety over a number field, the group () of K-rational points of is a finitely-generated abelian group, called the Mordell–Weil group.The case with an elliptic curve and the rational number field Q is Mordell's theorem, answering a question apparently posed by Henri Poincaré around 1901; it was proved by Louis Mordell in A sample application of Faltings' theorem is to a weak form of Fermat's Last Theorem: for any fixed {\displaystyle n>4} there are at most finitely many primitive integer solutions to {\displaystyle a^ {n}+b^ {n}=c^ {n}}, since for such {\displaystyle n} the curve Case g > 1: according to the Mordell conjecture, now Faltings's theorem, C has only a finite number of rational points. Proofs [ edit ] Shafarevich ( 1963 ) posed a finiteness conjecture that asserted that there are only finitely many isomorphism classes of abelian varieties of fixed dimension and fixed polarization degree over a fixed number field with good reduction outside a given finite Theorem (Faltings). Let K=Q be a number ﬁeld.

Notes on the ˙niteness theorem of Faltings for abelian varieties Wen-Wei Li Peking University November 14, 2018 Abstract These are informal notes prepared for the seminar on Faltings’ proof of the Mordell conjecture organized by Xinyi Yuan and Ruochuan Liu at Beijing International Center for Mathematical Research, Fall 2018. by Faltings [1983] (which asserts that a curve of genus greater than 1 de ned over a number eld has only a nite number of points rational over that number eld). As an example of an application of this theorem, choose your favorite polynomial g(x) with rational coe cients, no multiple roots, and of degree 5, for example g(x) = x(x 1)(x 2)(x 3)(x 4); Faltings’ theorem Let K be a number field and let C / K be a non-singular curve defined over K and genus g . When the genus is 0 , the curve is isomorphic to ℙ 1 (over an algebraic closure K ¯ ) and therefore C ⁢ ( K ) is either empty or equal to ℙ 1 ⁢ ( K ) (in particular C ⁢ ( K ) is infinite ). Faltings has been closely linked with the work leading to the final proof of Fermat's Last Theorem by Andrew Wiles.

Faltings's theorem In number theory, the Mordell conjecture is the conjecture made by Mordell (1922) that a curve of genus greater than 1 over the field Q of rational numbers has only finitely many rational points. In arithmetic geometry, the Mordell conjecture is the conjecture made by Mordell (1922) that a curve of genus greater than 1 over the field Q of rational numbers has only finitely many rational points. In 1983 it was proved by Gerd Faltings (1983, 1984), and is now known as Faltings's theorem. The conjecture was later generalized by replacing Q by any number field. Last Theorem by R.Taylor and A.Wiles Gerd Faltings T he proof of the conjecture mentioned in the title was finally completed in Septem-ber of 1994. A.

The conjecture was later generalized by replacing Q by any number field. It was proved by Gerd Faltings (1983), and is now known as The Isogeny theorem that abelian varieties with isomorphic Tate modules (as Q ℓ-modules with Galois action) are isogenous. A sample application of Faltings's theorem is to a weak form of Fermat's Last Theorem : for any fixed n > 4 there are at most finitely many primitive integer solutions (pairwise coprime solutions) to a n + b n = c n , since for such n Because of the Mordell-Weil theorem, Faltings' theorem can be reformulated as a statement about the intersection of a curve C with a finitely generated subgroup Γ of an abelian variety A. Generalizing by replacing C by an arbitrary subvariety of A and Γ by an arbitrary finite-rank subgroup of A leads to the Mordell-Lang conjecture, which has been proved.
