Title: Reduced bandwidth: a qualitative strengthening of twin-width in minor-closed classes (and beyond)

Speaker: O-joung Kwon Affiliation: Hanyang University Zoom: http://matroidunion.org/?page_id=2477 or contact Shayla Redlin

Abstract:

In a reduction sequence of a graph, vertices are successively identified until the graph has one vertex. At each step, when identifying $u$ and $v$, each edge incident to exactly one of $u$ and $v$ is coloured red.
