Locally Symmetric Families of Curves and Jacobians
In this paper we study locally symmetric families of curves and jacobians. By a locally symmetric family of jacobians, we mean a family of jacobians parameterized by a locally symmetric variety where the image of the period map is a locally symmetric subvariety of Ag[l], the moduli space of principally polarized abelian varieties of dimension g with a level l structure. A locally symmetric fami...
متن کاملCurves in Jacobians to Non - Jacobians Ii
This is a second paper where we introduce deformation theory methods which can be applied to finding curves in families of principally polarized abelian varieties (ppav) containing jacobians. One of our motivations for finding interesting and computationally tractable curves in ppav is to solve the Hodge conjecture for the primitive cohomology of the theta divisor which we explain below. For ot...
متن کاملCM Jacobians
1. Complex multiplication. We say an abelian variety A of dimension g over a field K admits sufficiently many Complex Multiplications (smCM) if D = End(A) contains a commutative semi-simple algebra Λ ⊂ D of rank dimQ(Λ) = [Λ : Q] = 2g. In this case we say A is a CM abelian variety. A point z ∈ Ag(k) is called a CM point if z is the moduli point of a polarized abelian variety z = [(A,μ)] such th...
متن کاملSeveral Parallel Algorithms for Solving Nonlinear Systems with Symmetric and Positive Definite Jacobians
In this work we describe two sequential algorithms and their parallel counterparts for solving nonlinear systems, when the Jacobian matrix is symmetric and positive definite. This case appears frequently in unconstrained optimization problems. Both algorithms are based on Newton’s method. The first solves the inner iteration with Cholesky decomposition while the second is based on the inexact N...
متن کاملOn maps between modular Jacobians and Jacobians of Shimura curves
Fix a squarefree integer N , divisible by an even number of primes, and let Γ be a congruence subgroup of level M , where M is prime to N . For each D dividing N and divisible by an even number of primes, the Shimura curve X(Γ0(N/D)∩Γ ) associated to the indefinite quaternion algebra of discriminant D and Γ0(N/D) ∩ Γ -level structure is well defined, and we can consider its Jacobian J(Γ0(N/D) ∩...
