This structure has been introduced to unify a theorem of Edmonds on the coverings of a matroid by independent sets and a theorem of Jackson on the existence of pairwise compatible Euler tours in a 4-regular graph. Here we investigate some basic concepts and properties related with multimatroids: matroid orthogonality, minor operations and connectivity.<\/jats:p>","DOI":"10.37236\/1346","type":"journal-article","created":{"date-parts":[[2020,1,10]],"date-time":"2020-01-10T20:59:25Z","timestamp":1578689965000},"source":"Crossref","is-referenced-by-count":7,"title":["Multimatroids II.
