OverviewThis book is a concise, self-contained, up-to-date introduction to extremal combinatorics for nonspecialists. There is a strong emphasis on theorems with particularly elegant and informative proofs, they may be called gems of the theory. The author presents a wide spectrum of the most powerful combinatorial tools together with impressive applications in computer science: methods of extremal set theory, the linear algebra method, the probabilistic method, and fragments of Ramsey theory. No special knowledge in combinatorics or computer science is assumed – the text is self-contained and the proofs can be enjoyed by undergraduate students in mathematics and computer science. Over 300 exercises of varying difficulty, and hints to their solution, complete the text. This second edition has been extended with substantial new material, and has been revised and updated throughout. It offers three new chapters on expander graphs and eigenvalues, the polynomial method and error-correcting codes. Most of the remaining chapters also include new material, such as the Kruskal—Katona theorem on shadows, the Lovász—Stein theorem on coverings, large cliques in dense graphs without induced 4-cycles, a new lower bounds argument for monotone formulas, Dvir's solution of the finite field Kakeya conjecture, Moser's algorithmic version of the Lovász Local Lemma, Schöning's algorithm for 3-SAT, the Szemerédi—Trotter theorem on the number of point-line incidences, surprising applications of expander graphs in extremal number theory, and some other new results.

The text is self-contained and assumes no special knowledge (only a standard mathematical background). Moreover, its 29 chapters each devoted to a particular proof technique are (almost) independent. Because of this modularity, its style and the character of its subject, this book can also be browsed and read for (mathematical) pleasure. (P. Schmitt, Monatshefte fur Mathematik, Vol. 141 (1), 2004) The book is structured as a collection of short, largely independent chapters, each dedicated to a specific proof technique. The book is broad in scope and gives equal space to the classical counting techniques and to more recent methods. I used the book to teach a small group of graduate students. It was a rewarding experience. The material was interesting, diverse, and challenging. this is a book I heart From the reviews of the second edition: This is an entertaining and impressive book. I say impressive because the author managed to cover a very large part of combinatorics in 27 short chapters, without assuming any graduate-level knowledge of the material. ... The collection of topics covered is another big advantage of the book. ... The book is ideal as reference material or for a reading course for a dedicated graduate student. One could teach a very enjoyable class from it as well ... . (Miklos Bona, The Mathematical Association of America, May, 2012) [R]eaders interested in any branch of combinatorics will find this book compelling. ... This book is very suitable for advanced undergraduate and graduate mathematics and computer science majors. It requires a very solid grounding in intermediate-level combinatorics and an appreciation for several proof methods, but it is well worth the study. (G.M. White, ACM Computing Reviews, May 2012) This is the second edition of a well-received textbook. It has been extended with new and updated results. Typographical errors in the first edition are corrected. ... This textbook is suitable for advanced undergraduate or graduate students as well as researchers working in discrete mathematics or theoretical computer science. The author's enthusiasm for the subject is evident and his writing is clear and smooth. This is a book deserving recommendation. (Ko-Wei Lih, Zentralblatt MATH, Vol. 1239, 2012) This is an introductory book that deals with the subject of extremal combinatorics. ... The book is nicely written and the author has included many elegant and beautiful proofs. The book contains many interesting exercises that will stimulate the motivated reader to get a better understanding of this area. ... author's goal of writing a self-contained book that is more or less up to date ... and that is accessible to graduate and motivated undergraduate students in mathematics and computer science, has been successfully achieved.

Cioaba, Mathematical Reviews, January, 2013) Author InformationThe author is a professor at the Goethe Universität Frankfurt and he is also a member of the Vilnius University Institute of Mathematics and Informatics. His main fields of research are theoretical computer science and discrete mathematics, in particular complexity. Tab Content 6Author Website:Countries AvailableAll regions |
