Title: Almost every matroid has a rank-3 wheel or rank-3 whirl as minor

Speaker: Jorn van der Pol
Affiliation: University of Waterloo
Zoom: http://matroidunion.org/?page_id=2477 or contact Shayla Redlin

Abstract:

Many conjectures – but few results – exist for the statistical properties of large "random" matroids. For example, the question which matroids appear as a minor of almost every matroid has been settled for only a few matroids.

Title: P-partition power sums

Speaker: Victor Wang
Affiliation: University of British Columbia
Room/Zoom: MC5479 or for Zoom link contact Logan Crew or Olya Mandelshtam

Abstract:

The Hopf algebra of symmetric functions is spanned by several important bases, including by power sum symmetric functions, which encode the class values of the characters of the symmetric group under the Frobenius characteristic map.

Title: The Chvátal-Gomory procedure for integer SDPs with applications in combinatorial optimization

Speaker: Frank de Meijer
Affiliation: Tilburg University
Location: MC 5501 or please contact Emma Watson for Zoom link

Abstract:

Semidefinite programs under the presence of integrality constraints are known as integer semidefinite programs (ISDPs). Since the combination of integrality and positive semidefiniteness leads to matrices that are highly structured, ISDPs have applications in several fields, including architecture and combinatorial optimization. In this project we consider the extension of the Chvátal-Gomory (CG) procedure, which is well-known for integer linear programming, to the class of ISDPs.

Tuesday, May 24, 2022 — 9:00 AM to Friday, May 27, 2022 — 4:30 PM EDT

A celebration of Goulden and Jackson's combined 90 years of insight and inspiration that have shaped the fields of algebraic and combinatorial enumeration.
