چکیده
Given a finite group G and an abelian variety A acted on by G, to any subgroup H of we associate subvariety AH which the associated Hecke algebra HH for in acts. Any irreducible rational representation W˜ induces natural way. In this paper give equations subvariety. special case these become much easier. We work out some examples.

Subvarieties of Abelian Varieties
Let (A; ) be a principally polarized abelian variety (ppav) of dimension g over the eld C of complex numbers. This means that is an ample divisor on A, well-determined up to translation, with h(A; ) := dimH(A; ) = 1. Let [ ] 2 H(A;Z) be the cohomology class of the theta divisor . Then the cohomology class [ ] e is divisible by (g e)!. The class [ ] g e (g e)! is not divisible and it is called t...
متن کاملLagrangian subvarieties of abelian fourfolds
Let (W, ω) be a smooth projective algebraic variety of dimension 2n over C together with a holomorphic (2, 0)-form of maximal rank 2n. A subvariety X ⊂ W is called weakly lagrangian if dim X ≤ n and if the restriction of ω to X is trivial (notice that X can be singular). An n-dimensional subvariety X ⊂ W with this property is called lagrangian. For example, any curve C contained in a K3 or abel...
متن کاملAbelian Subvarieties and the Shimura Construction
The purpose of this note is to show that the Shimura construction follows from a general “dictionary” that translates statements about subvarieties of abelian varieties into statements about ideals of the associated endomorphism algebras. Theorem. Let A/K be an abelian variety with endomorphism algebra E = End0K(A). Then the map B 7→ I(B) := {f ∈ E : Imf ⊂ B} defines an inclusion-preserving bij...
متن کاملThe Equations of Singular Loci of Ample Divisors on (subvarieties Of) Abelian Varieties
In this paper we consider ideal sheaves associated to the singular loci of a divisor in a linear system |L| of an ample line bundle on a complex abelian variety. We prove an effective result on their (continuous) global generation, after suitable twists by powers of L. Moreover we show that similar results hold for subvarieties of a complex abelian variety.
متن کاملEquidistribution of small subvarieties of an abelian variety
We prove an equidistribution result for small subvarieties of an abelian variety which generalizes the Szpiro–Ullmo–Zhang theorem on equidistribution of small points.
