可积系统的部分Fourier-Mukai变换及其在Hitchin纤维化中的应用

Partial Fourier--Mukai transform for integrable systems with applications to Hitchin fibration

Dima Arinkin, Roman Fedorov

摘要:

设X是方案B上的阿贝尔方案。Fourier-Mukai变换给出了X的导出范畴与对偶阿贝尔格式的导出范畴之间的等价性。我们部分扩展到某些计划X在B(我们称之为退化阿贝尔计划),其通用纤维是一个阿贝尔簇,而特殊纤维是奇异的。我们的主要结果提供了一个从Pic $^τ$(X/B)的导出范畴到X的导出范畴的完全忠实函子.这里Pic $^τ$(X/B)是分类纤维状数值平凡线丛的代数空间。其次,我们证明了每一个代数可积系统都产生一个退化的阿贝尔方案,并讨论了它在希钦系统中的应用。

英文摘要:

Let X be an abelian scheme over a scheme B. The Fourier--Mukai transform gives an equivalence between the derived category of X and the derived category of the dual abelian scheme. We partially extend this to certain schemes X over B (which we call degenerate abelian schemes) whose generic fiber is an abelian variety, while special fibers are singular. Our main result provides a fully faithful functor from a twist of the derived category of Pic$^τ$(X/B) to the derived category of X. Here Pic$^τ$(X/B) is the algebraic space classifying fiberwise numerically trivial line bundles. Next, we show that every algebraically integrable system gives rise to a degenerate abelian scheme and discuss applications to Hitchin systems.
