Algebraic and enumerative combinatorics seminar-Elana Kalashnikov
Title:The Abelian/non-Abelian correspondence and Littlewood-Richardson
| Speaker | Elana Kalashnikov |
| Affiliation | University of Waterloo |
| Location | MC 5479 |
Abstract:The Abelian/non-Abelian correspondence gives rise to a natural basis for the cohomology of flag varieties, which - except for Grassmannians - is distinct from the Schubert basis. I will describe this basis and its multiplication rules, and explain how to relate it to the Schubert basis for two-step flag varieties. I will then explain how this leads to new tableaux Littlewood--Richardson rules for many products of Schubert classes. This is joint work (separately) with Wei Gu and Linda Chen.
There will be a pre-seminar presenting relevant background at the beginning graduate level starting at 1:30pm,
Tutte colloquium-Sepehr Hajebi
Title:Complete bipartite induced minors (and treewidth)
| Speaker: | Sepehr Hajebi |
| Affiliation: | University of Waterloo |
| Location: | MC 5501 |
Abstract:I will present a result that describes the unavoidable induced subgraphs of graphs with a large complete bipartite induced minor, and will discuss the connections and applications to bounding the treewidth in hereditary classes of graphs. If time permits, I will also sketch some proofs.
Joint work with Maria Chudnovsky and Sophie Spirkl.
