Povzetek. 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.
