Extremal Finite Set Theory

"Materials collected in this book were meant to be presented at the Extremal Sets Systems Seminar of the Alfréd Rényi Institute of Mathematics. The main focus is placed on maximizing the cardinality of a family of sets satisfying some prescribed properties. The authors pay great attention to present a large range of proof techniques used in dealing with finite sets systems and give an extensive survey of recent results. Although ordinary graphs are 2-uniform families, extremal graph theory is outside the scope of this book. Ramsey-type theorems and coding theory are also avoided. The intended audience includes (1) students eager to learn the central topics on a graduate level; (2) university professors offering courses on extremal combinatorics; (3) researchers refreshing their knowledge and learning recent developments in the field. The book concludes with a comprehensive bibliography of 556 items. This makes it a convenient reference book for people interested in the latest developments in extremal finite set theory."

"This book gives a well-organized and timely summary of research directions in classical extremal combinatorics. As the title clari es, the focus excludes in nitary combinatorics. And, by the authors' own admission, results particular to extremal graph theory or coding theory are omitted. Instead, a considerable level of depth is o
ered on the status of the primary topics of extremal set theory: intersection theorems, Sperner families, Tur an problems, and saturation variants of these. The text is appropriate for graduate students or keen undergrads, and serves equally well as a comprehensive reference for researchers.

The book has over 500 insightful exercises which build on the presentation. These are especially valuable for young researchers in the subject, who can gain familiarity with the methods and connect various topics."
