Aimed at graduate students and researchers, this fascinating text
provides a comprehensive study of the Erdos-Ko-Rado Theorem, with a
focus on algebraic methods. The authors begin by discussing
well-known proofs of the EKR bound for intersecting families. The
natural generalization of the EKR Theorem holds for many different
objects that have a notion of intersection, and the bulk of this
book focuses on algebraic proofs that can be applied to these
different objects. The authors introduce tools commonly used in
algebraic graph theory and show how these can be used to prove
versions of the EKR Theorem. Topics include association schemes,
strongly regular graphs, the Johnson scheme, the Hamming scheme and
the Grassmann scheme. Readers can expand their understanding at
every step with the 170 end-of-chapter exercises. The final chapter
discusses in detail 15 open problems, each of which would make an
interesting research project.
