生成树与Kontsevich的一个猜想

Spanning trees and a conjecture of Kontsevich

Richard P. Stanley

摘要:

Kontsevich证明了与图G的生成树相连的多项式的q个元素的有限域上的零点个数f(G,q)是q的多项式函数.我们一直无法解决孔采维奇的猜想。然而,对于某些图G,例如完全图,我们可以显式地计算f(G,q)。我们还指出之间的联系Kontsevich的猜想和主题,如矩阵树定理和正交几何。

英文摘要:

Kontsevich conjectured that the number f(G,q) of zeros over the finite field with q elements of a certain polynomial connected with the spanning trees of a graph G is polynomial function of q. We have been unable to settle Kontsevich's conjecture. However, we can evaluate f(G,q) explicitly for certain graphs G, such as the complete graph. We also point out the connection between Kontsevich's conjecture and such topics as the Matrix-Tree Theorem and orthogonal geometry.
