Jason I. Brown is a professor of mathematics at Dalhousie University. He received a Ph.D. from the University of Toronto and has written over 70 refereed articles. His research interests include graphs, hypergraphs, partial order, finite topologies, and simplicial complexes, with a focus on the applications of other fields of mathematics to discrete problems. His mathematical research that uncovered how the Beatles played the opening chord of A Hard Day's Night was featured in various media, including NPR and BBC radio, Guitar Player Magazine, and the Wall Street Journal website.
The book is a collection of examples, each of which shows either how discrete structures interact with each other or how discrete structures interact with other parts of mathematics. ... I am certain I will use some examples I found in this book when I teach combinatorics in the upcoming semester. -Miklos Bona, MAA Reviews, December 2013
