Prym品种的尺寸

Dimensions of Prym Varieties

Amy E. Ksir

摘要:

给定曲线pi:X -> Y的驯服Galois分支覆盖,其中有限伽罗瓦群G的表示是有理数的,我们计算了G的任何不可约表示ρ对应的(广义)Prym簇的维数.这个公式可以应用于使用Lax对的代数可积系统的研究,特别是与Seiberg-Witten理论相关的系统。然而,该公式更一般,其计算和证明完全是代数的。

英文摘要:

Given a tame Galois branched cover of curves pi: X -> Y with any finite Galois group G whose representations are rational, we compute the dimension of the (generalized) Prym variety corresponding to any irreducible representation ρof G. This formula can be applied to the study of algebraic integrable systems using Lax pairs, in particular systems associated with Seiberg-Witten theory. However, the formula is much more general and its computation and proof are entirely algebraic.
