与图的和相关的动机

Motives associated to sums of graphs

Spencer Bloch

摘要:

与图形相关联的费曼振幅是特定动机的周期。在Grothendieck簇环中定义了所有不含重边或蝌蚪的n个顶点的连通图上这些运动类的和。这个和位于由仿射直线生成的子环中。它遵循从工作的Belkale和布鲁斯南的动机个别图不在于这个子环。

英文摘要:

The Feynman amplitude associated to a graph is a period of a certain motive. The sum of these motive classes over all connected graphs with no multiple edges or tadpoles and n vertices is defined in the Grothendieck ring of varieties. This sum is shown to lie in the subring generated by the affine line. It follows from work of Belkale and Brosnan that motives of individual graphs do not lie in this subring.
