George "], "item_description" : "What Is Combinatorics Anyway?Broadly speaking, combinatorics is the branch of mathematics dealingwith different ways of selecting objects from a set or arranging objects. Ittries to answer two major kinds of questions, namely, counting questions: how many ways can a selection or arrangement be chosen with a particular set of properties; and structuralquestions: does there exist a selection or arrangement of objects with aparticular set of properties?The authors have presented a text for students at all levels of preparation.For some, this will be the first course where the students see several real proofs.Others will have a good background in linear algebra, will have completed the calculusstream, and will have started abstract algebra.The text starts by briefly discussing several examples of typical combinatorial problemsto give the reader a better idea of what the subject covers. The nextchapters explore enumerative ideas and also probability. It then moves on toenumerative functions and the relations between them, and generating functions and recurrences.,Important families of functions, or numbers and then theorems are presented.Brief introductions to computer algebra and group theory come next. Structures of particularinterest in combinatorics: posets, graphs, codes, Latin squares, and experimental designs follow. Theauthors conclude with further discussion of the interaction between linear algebraand combinatorics.FeaturesTwo new chapters on probability and posets.Numerous new illustrations, exercises, and problems.More examples on current technology useA thorough focus on accuracyThree appendices: sets, induction and proof techniques, vectors and matrices, and biographies with historical notes,Flexible use of MapleTM and MathematicaTM", "item_img_path" : "https://covers2.booksamillion.com/covers/bam/1/49/877/760/1498777600_b.jpg", "price_data" : { "retail_price" : "165.00", "online_price" : "165.00", "our_price" : "165.00", "club_price" : "165.00", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
