1. Hiperplanos conexos em matrÃides binÃrias
Non-separating circuits and cocircuits play an important role in the understanding of the structure of graphic matroids. For example, using this concept Tutte [27] characterized the 3-connected graphs which are planar. Bixby and Cunningham [2] generalized Tutteâs result for the class of binary matroids. Kelmans [11] and, independently, Seymour (see [16]) pr
