Minimal non-orientable matroids in a projective plane
Rigoberto Florez, David Forge
We construct a new family of minimal non-orientable matroids of rank three. Some of these matroids embed in Desarguesian projective planes. This answers a question of Ziegler: for…
Lindström's conjecture on a class of algebraically non-representable matroids
Rigoberto Florez
Gordon introduced a class of matroids , for prime , such that is algebraically representable, but only in characteristic . Lindström proved that for…
Harmonic Conjugation in Harmonic Matroids
Rigoberto Florez
We study a generalization of the concept of harmonic conjugation from projective geometry and full algebraic matroids to a larger class of matroids called \emph{harmonic matroids}.…
Irreducibility of generalized Fibonacci polynomials
Rigoberto Florez, J. C. Saunders
A second order polynomial sequence is of Fibonacci-type (Lucas-type ) if its Binet formula has a structure similar to that for Fibonacci (Lucas)…
