On January 25, 2022, O-joung Kwon (권오정) from the Incheon National University / IBS Discrete Mathematics Group gave a talk at the Discrete Math Seminar on upper bounds of the twin-width and reduced-bandwidth of planar graphs and H-minor-free graphs at the Discrete Math Seminar. The title of his talk was “Reduced bandwidth: a qualitative strengthening of twin-width in minor-closed classes (and beyond)“.
