WebFeb 4, 2024 · Using that the rank function of a q-matroid is fully determined by the cyclic flats and their ranks, we show that the cyclic flats of the direct sum of two q-matroids are exactly all the direct sums of the cyclic flats of the two summands. This simplifies the rank function of the direct sum significantly. A q-matroid is called irreducible if it ... WebApr 5, 2024 · The Cyclic Flats of a. -Matroid. Gianira N. Alfarano, Eimear Byrne. In this paper we develop the theory of cyclic flats of -matroids. We show that the lattice of cyclic flats, together with their ranks, uniquely determines a -matroid and hence derive a new -cryptomorphism. We introduce the notion of -independence of an -subspace of and we … cyberoam subscription

Note that the graph (V,F) has various connected components. Then, loosely speaking, F forms a flat in a graphic matroid if adding any edge to F reduces this number of connected components. More precisely, we let Π be a … cheap notebooks for school
