This volume contains nine survey articles based on plenary lectures
given at the 28th British Combinatorial Conference, hosted online by
Durham University in July 2021. This biennial conference is a
well-established international event, attracting speakers from around
the world. Written by some of the foremost researchers in the field,
these surveys provide up-to-date overviews of several areas of
contemporary interest in combinatorics. Topics discussed include maximal
subgroups of finite simple groups, Hasse-Weil type theorems and relevant
classes of polynomial functions, the partition complex, the graph
isomorphism problem, and Borel combinatorics. Representing a snapshot of
current developments in combinatorics, this book will be of interest to
researchers and graduate students in mathematics and theoretical
computer science.
