Gauss-Manin行列式联络与非正则联络的周期

Gauß-Manin determinant connections and periods for irregular connections

Spencer Bloch, Hélène Esnault

摘要:

研究了与曲线上的不规则联络相联系的Gauwan-Manin行列式联络.计算了不规则连接的傅里叶变换的行列式。标准秩为2的Kloosterman层的上同调行列式是模2挠计算的。在非常基本的$\exp(f)$情况下研究了与不规则连接相关的周期,并讨论了与Gauss-Manin行列式的类比。

英文摘要:

Gauß-Manin determinant connections associated to irregular connections on a curve are studied. The determinant of the Fourier transform of an irregular connection is calculated. The determinant of cohomology of the standard rank 2 Kloosterman sheaf is computed modulo 2 torsion. Periods associated to irregular connections are studied in the very basic $\exp(f)$ case, and analogies with the Gauß-Manin determinant are discussed.
