Tuza's conjecture for binary geometries

Kazuhiro Nomoto, Jorn van der Pol

Tuza (A conjecture, in Proceedings of the Colloquia Mathematica Societatis Janos Bolyai, 1981) conjectured that for all graphs , where is the minimum siz…

The critical number of -free triangle-free binary matroids

Peter Nelson, Kazuhiro Nomoto

A simple binary matroid, viewed as a restriction of a finite binary projective geometry , is -free if for any rank- flat of , its intersection wit…

The smallest -free and triangle-free binary matroids

Peter Nelson, Kazuhiro Nomoto

We determine the smallest simple triangle-free binary matroids that have no five-element independent flat. This solves a special case of a conjecture of Nelson and Norin.

The structure of -free and triangle-free binary matroids

Peter Nelson, Kazuhiro Nomoto

A simple binary matroid is called -free if none of its rank-4 flats are independent sets. These objects can be equivalently defined as the sets of points in fo…

The structure of claw-free binary matroids

Peter Nelson, Kazuhiro Nomoto

A simple binary matroid is called claw-free if none of its rank-3 flats are independent sets. These objects can be equivalently defined as the sets of points in $\mathrm{PG}(n-…

Stability and exact Turan numbers for matroids

Hong Liu, Sammy Luo, Peter Nelson +1

We consider the Turán-type problem of bounding the size of a set that does not contain a linear copy of a given fixed set ,…
