Title: Presenting a tangle
Speaker: | Jim Geelen |
Affiliation: | University of Waterloo |
Room: | MC 5417 |
Abstract: A tangle of order $k$ in a matroid is an abstract notion that describes a “$k$-connected component” of a matroid. Tangles are very useful in theoretical applications, but in practice they suffer from being difficult to describe succinctly. In this talk we try to address that issue and present some negative results.
