Local to global principles for homomorphisms of abelian schemes

, 2023
Let $A$ and $B$ be abelian varieties defined over the function field $k(S)$ of a smooth algebraic variety $S/k.$ We establish criteria, in terms of restriction maps to subvarieties of $S,$ for existence of various important classes of $k(S ...

Varieties of Metabelian Lie Algebras over Finite Fields

, 1986
[Drensky Vesselin S.; Дренски Веселин С.]Metabelian varieties of Lie algebras over a finite field are studied in this paper. It is proved that any such variety is a union of two subvarieties.

Special subvarieties in the locus of intermediate Jacobians of cubic threefolds

, 2023
We study special subvarieties, i.e., subvarieties containing a dense subset of CM points, of the moduli space $A_5$ of principally polarized abelian varieties of dimension five, generically contained in the locus of intermediate Jacobians of cubic ...

P-compatible Abelian groups

, 2005
Let τ : F → N be a type of a variety V . Every partition P of the set F determines a so-called P-compatible variety. We consider the varieties GnP defined by so-called P-compatible identities of Abelian groups with exponent n.

Decomposing abelian varieties into simple factors: algorithms and applications

We give an effective procedure to explicitly find the decomposition of a polarized abelian variety into its simple factors if a period matrix is known. Since finding this datum is not easy, we also provide two methods to compute the period matrix for a ...

The André-Pink conjecture (Hecke orbits and weakly special subvarieties)

, 2013
La conjecture d'André-Pink affirme qu'une sous-variété d'une variété de Shimura ayant une intersection dense avec une orbite de Hecke est faiblement spéciale. On démontre cette conjecture dans le cas de courbes dans une variété de Shimura de type abélien,
