Title: Widths in even-hole-free graphs

Speaker: Nicolas Trotignon Affiliation: CNRS - LIP - École Normale Supérieure de Lyon Zoom: Please email Emma Watson

Abstract:

Historically, the study of even-hole-free graphs is motivated by the analogy with perfect graphs. The decomposition theorems that are known for even-hole-free graphs are seemingly more powerful than the ones for perfect graphs: the basic classes and the decompositions are in some respect more restricted. But strangely, in an algorithmic perpective, much more is known for perfect graphs.
