WebRecall that an abelian variety over a complete field K is said to have potentially good reductionif there exists a finite field extensionL/K such that the base change of A to L is the generic fiber of an abelian scheme over the valuation ring of L. If R is any Dedekind domain with quotient field K, we will say that an abelian variety A/K Web7 de mai. de 2012 · We show that there do not exist any non-zero semi-stable abelian varieties over Q with good reduction outside l if and only if l=2, 3, 5, 7 or 13.

We will see that A∼B ⇒ π A∼π B, i.e. abelian varieties defined over the same finite field Kisogenous over Kdefine conjugated Weil numbers. We will write {simple abelian variety over K}/∼ K =: M(K,s) for the set of isogeny classes of simple abelian ...
WebAs the reduction behavior is determined by the Galois representations of the decompositon groups, one can reformulate the problem as follows: let A be an abelian variety over F, p a fixed rational prime, V the p-adic Tate module of A; and for λ primes of F, ρ λ is the p -adic representation on V of the decomposition group G λ at λ.
