Poset dimension and maximum comparability degree

Carla Groenland, Richard Montgomery, Rajko Nenadov +1

In 1986, Füredi and Kahn showed that the dimension $dim (P)$ of any finite poset $P$ satisfies $dim (P) = O (d lo g^{2} d)$ , where $d$ is the maximum degree of the comparability graph…

Asymptotically-tight packing and covering with transversal bases in Rota's basis conjecture

Richard Montgomery, Lisa Sauermann

In 1989, Rota conjectured that, given any $n$ bases $B_{1}, \dots, B_{n}$ of a vector space of dimension $n$ , or more generally a matroid of rank $n$ , it is possible to rearrange these i…

Almost-full transversals in equi- $n$ -squares

Debsoumya Chakraborti, Micha Christoph, Zach Hunter +2

In 1975, Stein made a wide generalisation of the Ryser-Brualdi-Stein conjecture on transversals in Latin squares, conjecturing that every equi- $n$ -square (an $n \times n$ array fill…

Packing the largest trees in the tree packing conjecture

Barnabás Janzer, Richard Montgomery

The famous tree packing conjecture of Gyárfás from 1976 says that any sequence of trees $T_{1}, \dots, T_{n}$ such that $∣ T_{i} ∣ = i$ for each $i \in [n]$ packs into the complete $n$ -vertex…

A proof of the Ryser-Brualdi-Stein conjecture for large even $n$

Richard Montgomery

A Latin square of order $n$ is an $n$ by $n$ grid filled using $n$ symbols so that each symbol appears exactly once in each row and column. A transversal in a Latin square is a col…
