CW复形、Tutte拟多项式和算术拟阵上的着色与流

Colorings and flows on CW complexes, Tutte quasi-polynomials and arithmetic matroids

Emanuele Delucchi, Luca Moci

摘要:

在这份说明中,我们提供了一个高维模拟Tutte的著名定理的着色和流动的图,通过表明,理论的算术Tutte多项式和准多项式包括不变量定义的CW复杂的贝克-布鲁尔-Godkin-Martin和Duval-Klivans-Martin。此外,我们回答了一个问题,巴约Burdick Chmutov,关于修改Tutte,Krushkal,Renhardy多项式定义的这些作者:为此,我们证明了产品的两个算术重函数的拟阵再次是一个算术重函数。

英文摘要:

In this note we provide a higher-dimensional analogue of Tutte's celebrated theorem on colorings and flows of graphs, by showing that the theory of arithmetic Tutte polynomials and quasi-polynomials encompasses invariants defined for CW complexes by Beck-Breuer-Godkin-Martin and Duval-Klivans-Martin. Furthermore, we answer a question by Bajo-Burdick-Chmutov, concerning the modified Tutte-Krushkal-Renhardy polynomials defined by these authors: to this end, we prove that the product of two arithmetic multiplicity functions on a matroid is again an arithmetic multiplicity function.
