Separating cocircuits in binary matroids

Linear Algebra and its Applications, 1982
AbstractA cocircuit of a matroid is separating if deleting it leaves a separable matroid. We give an effecient algorithm which finds a separating cocircuit or a Fano minor in a binary matroid, thus proving constructively a theorem of Tutte. Using this algorithm and a new recursive characterization of bond matroids, we give a new method for testing ...

Note on binary simplicial matroids

Discrete Mathematics, 1984
Binary simplicial matroids are characterized among binary matroids. Using lemma 2: ''A binary simplicial matroid has a base whose associated fundamental hypergraph is isomorphic to a simplicial hypergraph.'', and a previous characterization of simplicial hypergraphs.
