域上拟阵的向量

Vectors of matroids over tracts

Laura Anderson

摘要:

我们丰富了贝克和鲍勒的理论拟阵的向量和余向量的概念。在定向拟阵的情况下,这些$F$ -向量和$F$ -余向量与通常的符号向量和符号余向量重合。在域$F$上的拟阵的情况下,$F$ -共向量集分别为:一个$F$ -拟阵的$F$ -向量集是$F^E$的线性子空间.它的正交补。

英文摘要:

We enrich Baker and Bowler's theory of matroids over tracts with notions of vectors and covectors. In the case of oriented matroids, these $F$-vectors and $F$-covectors coincide with the usual signed vectors and signed covectors. In the case of matroids over a field $F$, the $F$-covector set resp. $F$-vector set of an $F$-matroid is a linear subspace of $F^E$ resp. its orthogonal complement.
