本文导出了单参数代数簇族的l-adic欧拉特征线的一个公式。我们定义了一个代数模拟的孤立奇点的代数超曲面,定义在复杂的情况下由米尔诺的局部单值。我们讨论了与代数簇族的导体的定义有关的各种代数。参考书目:26项。
In this paper we derive a formula for the l-adic Euler characteristic of a one-parameter family of algebraic varieties. We define an algebraic analog of the local monodromy of isolated singularities of algebraic hypersurfaces, defined in the complex case by Milnor. We discuss various conjectures connected with the definition of the conductor of a family of algebraic varieties. Bibliography: 26 items.
