拟阵与定向拟阵的模消去

Modular elimination in matroids and oriented matroids

Emanuele Delucchi

摘要:

我们引入了一个新的公理化拟阵理论,需要消除属性之间的模块化对电路,我们提出了一个cryptomorphic措辞的Crapo的公理单位。这种新的观点导致相应的加强电路公理的定向拟阵。

英文摘要:

We introduce a new axiomatization of matroid theory that requires the elimination property only among modular pairs of circuits, and we present a cryptomorphic phrasing thereof in terms of Crapo's axioms for flats. This new point of view leads to a corresponding strengthening of the circuit axioms for oriented matroids.
