Detecting minors in matroids through triangles
Boris Albar, Daniel Gonçalves, Jorge L. Ramírez Alfonsín
In this note we investigate some matroid minor structure results. In particular, we present sufficient conditions, in terms of {\em triangles}, for a matroid to have either $U_{2,4…

Boris Albar, Daniel Gonçalves, Kolja Knauer
We prove that any triangulation of a surface different from the sphere and the projective plane admits an orientation without sinks such that every vertex has outdegree divisible b…
