Cardinality Homogeneous Set Systems, Cycles in Matroids, and Associated Polytopes
A subset C of the power set of a finite set E is called cardinality homogeneous if, whenever C contains some set F , C contains all subsets of E of cardinality |F |. Examples of such set systems C are the sets of all even or of all odd cardinality subsets of E, or, for each uniform matroid, its set of circuits and its set of cycles. With each cardinality homogeneous set system C, we associate t...
متن کاملSpanning cycles in regular matroids without M*(K5) minors
Catlin and Jaeger proved that the cycle matroid of a 4-edge-connected graph has a spanning cycle. This result can not be generalized to regular matroids as there exist infinitely many connected cographic matroids, each of which contains a M(K5) minor and has arbitrarily large cogirth, that do not have spanning cycles. In this paper, we proved that if a connected regular matroid without aM(K5)-m...
متن کاملSpanning cycles in regular matroids without small cocircuits
A cycle of a matroid is a disjoint union of circuits. A cycle C of a matroidM is spanning if the rank of C equals the rank ofM . Settling an open problem of Bauer in 1985, Catlin in [P.A. Catlin, A reduction method to find spanning Eulerian subgraphs, J. Graph Theory 12 (1988) 29–44] showed that if G is a 2-connected graph on n > 16 vertices, and if δ(G) > n 5−1, thenGhas a spanning cycle. Catl...
متن کاملCATEGORICAL RELATIONS AMONG MATROIDS, FUZZY MATROIDS AND FUZZIFYING MATROIDS
The aim of this paper is to study the categorical relations betweenmatroids, Goetschel-Voxman’s fuzzy matroids and Shi’s fuzzifying matroids.It is shown that the category of fuzzifying matroids is isomorphic to that ofclosed fuzzy matroids and the latter is concretely coreflective in the categoryof fuzzy matroids. The category of matroids can be embedded in that offuzzifying matroids as a simul...
