Signature Defects and Eta Functions of Degenerations of Abelian Varieties
نویسنده
چکیده
In this paper, we will calculate the eta functions for torus bundles over S 1 which arise from boundaries of degenerations of Abelian varieties when the local monodromies are unipotent or have nite orders. By using the special values of the eta functions, we obtain the signature defects for such degenerations.

متن کاملCompactifications of Moduli of Abelian Varieties: an Introduction
In this expository paper, we survey the various approaches to compactifying moduli stacks of polarized abelian varieties. To motivate the different approaches to compactifying, we first discuss three different points of view of the moduli stacks themselves. Then we explain how each point of view leads to a different compactification. Throughout we emphasize maximal degenerations which capture m...

Since the mid 1980’s, abelian varieties have been widely used in cryptography: the discrete logarithm problem and the protocols that rely on it allow asymmetric encryption, signatures, authentification... For cryptographic applications, one of the most interesting examples of principally polarized abelian varieties is given by the Jacobians of hyperelliptic curves. The theory of theta functions...
متن کاملChow-künneth Decomposition for Universal Families over Picard Modular Surfaces
We discuss conditions for the existence of an absolute ChowKünneth decomposition for complete degenerations of families of Abelian threefolds with complex multiplication over a particular Picard Modular Surface studied by Holzapfel. In addition to the work of Gordon, Hanamura and Murre we use Relatively Complete Models in the sense of Mumford-Faltings-Chai of Picard Modular Surfaces in order to...
