Duksang Lee (이덕상) gave a talk on intertwining connectivities for vertex-minors and pivot-minors of graphs at the Discrete Math Seminar

On August 10, 2021, Duksang Lee (이덕상) from KAIST and IBS Discrete Mathematics Group gave a talk at the Discrete Math Seminar, showing that there are finitely many pivot-minor-minimal graphs preserving the rank connectivity between two fixed pairs of vertex sets. The title of his talk was “Intertwining connectivities for vertex-minors and pivot-minors“.
