曲面图的多项式不变量

Polynomial invariants of graphs on surfaces

R. Askanazi, S. Chmutov, C. Estill, J. Michel, P. Stollenwerk

摘要:

对于嵌入到曲面中的图,我们将图的圈拟阵和对偶图的键拟阵的许多组合参数与嵌入的拓扑参数联系起来。这将给出多项式的表达式,由M.Las Vergnas以组合的方式使用拟阵作为Krushkal多项式的特殊化来定义,使用表面的第一个同调群中的辛结构来定义。

英文摘要:

For a graph embedded into a surface, we relate many combinatorial parameters of the cycle matroid of the graph and the bond matroid of the dual graph with the topological parameters of the embedding. This will give an expression of the polynomial, defined by M.Las Vergnas in a combinatorial way using matroids as a specialization of the Krushkal polynomial, defined using the symplectic structure in the first homology group of the surface.
