Let $\mathrm{C}_A(M)$ denote the arc complexity of a gammoid $M=(E,\mathcal{I})$, where $|E|$ is its ground-set size. Unbounded arc-complexity conjecture for gammoids. For every…

Let $r,n\to\mathbb{N}$ with $n\geq r$. The uniform matroid of rank $r$ on $n$ elements is $U_{r,n}=({\{1,2,\ldots,n\}},\mathcal{I}_{r,n})$, where … Let $T=\{1,2,\ldots,r\}$,…
