Tilen Marc: A graph theoretical approach towards some open problems about oriented matroids
Datum objave: 10. 12. 2018
Seminar za diskretno matematiko
Torek, 11. 12. 2018, od 10h do 12h, Plemljev seminar, Jadranska 19Povzetek. In the talk we will present some long standing open problems about oriented matroids namely Las Vergnas conjecture and a conjecture about connectivity of so called mutation graphs. Both problems arise from the geometric view of oriented matroids but we will approach them as graph theoretical problems presenting some new results on the topic.
