Dillon Mayhew, Mike Newman, Geoff Whittle

A minor-closed class of matroids is (strongly) fractal if the number of n-element matroids in the class is dominated by the number of n-element excluded minors. We conjecture that…

On Density-Critical Matroids

Rutger Campbell, Kevin Grace, James Oxley +1

For a matroid $M$ having $m$ rank-one flats, the density $d (M)$ is $\frac{m}{r ( M )}$ unless $m = 0$ , in which case $d (M) = 0$ . A matroid is density-critical if all of its proper min…
