Home Page for the Book "A=B" by Marko Petkovsek Herbert Wilf and Doron Zeilberger with a Foreword by Donald E. Knuth (read it below) YOU CAN NOW DOWNLOAD THE ENTIRE BOOK About the Book "A=B" is about identities in general, and hypergeometric identities in particular, with emphasis on computer methods of discovery and proof. The book describes a number of algorithms for doing these tasks, and we intend to maintain the latest versions of the programs that carry out these algorithms on this page. So be sure to consult this page from time to time, and help yourself to the latest versions of the programs. In addition to programs, we will post here other items of interest relating to the book, such as the current errata sheet (see below). The other side of the coin is that we invite your comments about the content of the book, the programs, any errors that you may discover, or whatever. You can send us your comments by e-mail if you wish. The book is a selection of the Library of Science. A Japanese translation of A=B, by Toppan Co., Ltd., appeared in November of 1997.

Hsiao , August 2003 Advisor: Louis Billera Quasisymmetric Functions and Flag Enumeration in Eulerian Posets Abstract: We study the algebraic and enumerative combinatorial aspects of Eulerian posets and their quasisymmetric generating functions. These generating functions span the so-called peak algebra Pi, which originated with Stembridge's theory of enriched P -partitions. Remarkably, many constructs in the peak algebra that are natural in the context of enriched P -partitions are also important from the viewpoint of flag enumeration. For example, we show that the fundamental basis of peak functions arising from enriched P -partitions of chains is precisely the basis that is needed to properly encode the cd -index, a common invariant in the study of convex polytopes and Eulerian posets. As another example, the descents-to-peaks map, which relates the ordinary and enriched theories of P -partitions, turns out to be important for computing the flag-enumerative information of an oriented matroid based on that of the underlying matroid.

Combinatorics From Wikinfo Jump to: navigation search Combinatorics is a branch of mathematics that studies finite collections of objects that satisfy certain criteria, and is in particular concerned with "counting" the objects in those collections ( enumerative combinatorics ) and with deciding whether certain "optimal" objects exist ( extremal combinatorics ). One of the most prominent combinatorialists of recent times was Gian-Carlo Rota , who helped formalize the subject beginning in the . The prolific problem-solver worked mainly on extremal questions. The study of how to count objects is sometimes thought of separately as the field of enumeration A quite comprehensive listing by page is list of combinatorics topics An example of a combinatorial question is the following: What is the number of possible orderings of a deck of 52 playing cards? That number equals 52! (i.e., "fifty-two factorial , is so large. That is a little bit more than 8 followed by 67 zeros. Comparing that number to some other large numbers, it is greater than the square of Avogadro's number , "the number of atoms, molecules, etc., in a gram mole".

Summer School ALCCAL' 2000 "ALGEBRAIC COMBINATORICS AND COMPUTER ALGEBRA" September 3 - 14, 2000, Varna, BULGARIA First Announcement Place of the ALCCAL'2000 Summer School Main idea Scientific Community Structure of the meeting Method of organization ... Important dates Main idea We are organizing a summer school with the above title in Bulgaria on the coast of Black Sea from September 3 to September 14, 2000. The duration of the summer school will be 12 days, including 8 working days, 2 excursion days and days of arrival and departure. Sponsorship was not sought for the meeting and so we are unable to give any financial support to the participants. Everything is based on the enthusiasm of the organizers and our guests. In a sense the idea of this meeting is similar to the idea of the First International Conference on Algebraic Combinatorics in Vladimir, USSR, August 1991. We think that the present time in Bulgaria is most appropriate: this country is striving to become a major tourist and recreational attraction. Thus we have been able to find reasonable prices at a high level of service. Scientific community Roughly speaking, algebraic combinatorics deals with highly symmetrical combinatorial objects (graphs, designs, codes etc.). What "high symmetry" means can be rigorously formulated in terms of the action of the automorphism group of the object. One of the most beneficial ways to consider this is that the requirement of transitivity (primitivity) of the action of a certain group is substituted by weaker assumption of combinatorial regularity. For example, parallel consideration and classification of rank 3 graphs and strongly regular graphs is one of the areas in algebraic combinatorics. The techniques used in algebraic combinatorics is in a sense an amalgamation of methods from group theory, linear algebra, graph theory, number theory and representation theory. Extensive use of computers and especially of computer algebra packages is an essential feature of this area.

It can also be obtained recursively through the Fibonacci recurrence relation. Calculating the number of ways that certain patterns can be formed is part of the field of combinatorics . In this section, we introduce useful counting techniques that can be applied to situations pertinent to probability theory. Contents The Counting Principle Permutations Stirling's Formula k-Permutations ... edit The Counting Principle The Fundamental Rule of Counting If a set of choices or trials, T1, T2, T3, …, Tk, could result, respectively, in n1, n2, n3, …,nk possible outcomes, the entire set of k choices or trials has n1×n2×n3× … ×nk possible outcomes. (The numbers n1, n2, n3, …, nk cannot depend on which outcomes actually occur.) By the Fundamental Rule of Counting, the total number of possible sequences of choices is 5×4×3×2×1 = 120 sequences. Each sequence is called a permutation of the five items. A permutation of items is an ordering of the items. More generally, by the Fundamental Rule of Counting, in ordering n things, there are n choices for the first, (n-1) choices for the second, etc., so the total number of ways of ordering a total of n things is n × (n-1) × (n-2) × . . . × 1. This product, n×(n-1)×(n-2)× . . . ×1, is written n!, which is pronounced "n factorial." By convention, 0! = 1
