Matroids related to groups and semigroups
Abstract
Matroid is defined as a pair $$$(X,\mathcal{I})$$$, where $$$X$$$ is a nonempty finite set, and $$$\mathcal{I}$$$ is a nonempty set of subsets of $$$X$$$ that satisfies the Hereditary Axiom and the Augmentation Axiom. The paper investigates for which semigroups (primarily finite) $$$S$$$, the pair $$$(\widehat{S}, \mathcal{I})$$$ will be a matroid.
