Abelian variety

36: 960:, for any nonzero prime of your Dedekind domain, there is a map from the Dedekind domain to the quotient of the Dedekind domain by the prime, which is a finite field for all finite primes. This induces a map from the fraction field to any such finite field. Given a curve with equation defined over the number field, we can apply this map to the coefficients to get a curve defined over some finite field, where the choices of finite field correspond to the finite primes of the number field. 114: 1800:
In the early 1940s, Weil used the first definition (over an arbitrary base field) but could not at first prove that it implied the second. Only in 1948 did he prove that complete algebraic groups can be embedded into projective space. Meanwhile, in order to make the proof of the

Abelian varieties are at the same time among the most studied objects in algebraic geometry and indispensable tools for research on other topics in algebraic geometry and number theory. 3920:-torsion points generate number fields with very little ramification and hence of small discriminant, while, on the other hand, there are lower bounds on discriminants of number fields. 3487: 3731: 3558: 2556: 3381: 2826: 2184: 3532: 2729: 3132: 2443: 2404: 4122: 3863: 1856: 1791: 559: 534: 497: 3423: 2690: 2659: 2509: 2478: 2356: 2311: 1392: 1449: 3170: 1697: 1269: 4030: 3918: 3319: 3251:.
