Let be a collection of not necessarily distinct ‐vertex graphs with the same vertex set . We use to denote an edge‐colored multigraph of with and a multiset consisting of , and the edge of ...
A cycle of a matroid is a disjoint union of circuits. A matroid is supereulerian if it contains a spanning cycle. To answer an open problem of Bauer in 1985, Catlin proved in [J. Graph Theory 12 (1988) 29–44] that for sufficiently large , every 2‐edge‐connected simple graph with and minimum degree is supereulerian. In...
