A conference in honour of Bill Cunningham's 65th birthday

Overview

Bill CunnignhamMatroid theory and matching theory are among the oldest and most established areas in combinatorics, so progress in these areas is typically hard won; nevertheless, the recent advances have been spectacular. There is now an efficient algorithm for solving the weighted matroid matching problem for linear matroids. The 25-year old conjecture that bridgeless cubic graphs have exponentially many perfect matchings has been proved. Groundbreaking approximation algorithms for the graphical travelling salesman problem rely crucially on significant new insights on matching and T-joins. The graph minors project has been extended to binary matroids. And, a 40-year old unimodality conjecture has been proved for linear matroids.

Matroids and matching are two areas that lie close to Bill Cunningham's heart, and these advances provide the perfect backdrop to a Conference celebrating Bill's 65th birthday. As with Bill's interests, the topics covered in the conference are not limited to matching and matroids.

Some photographs from the conference banquet are now available.
