How many delta-matroids are there?

Daryl Funk, Dillon Mayhew, Steven D. Noble

We give upper and lower bounds on the number of delta-matroids, and on the number of even delta-matroids.

Matrix representations of frame and lifted-graphic matroids correspond to gain functions

Daryl Funk, Irene Pivotto, Daniel Slilaty

Let $M$ be a 3-connected matroid and let $F$ be a field. Let $A$ be a matrix over $F$ representing $M$ and let $(G, B)$ be a biased graph representing $M$ .…

Almost balanced biased graph representations of frame matroids

Matt DeVos, Daryl Funk

Given a 3-connected biased graph $Ω$ with a balancing vertex, and with frame matroid $F (Ω)$ nongraphic and 3-connected, we determine all biased graphs $Ω^{'}$ with $F (Ω^{'}) = F (Ω)$ . As…
