In addition to covering all the standard techniques for counting combinatorial objects, the text contains material from the research literature which has never before appeared in print, such as the use of quotient posets to study the Möbius function and characteristic polynomial of a partially ordered set, or the connection between quasisymmetric functions and pattern avoidance.The book assumes minimal background, and a first course in abstraPPN: PPN: 1755153538Package identifier: Produktsigel: BSZ-4-NLEBK-KAUB | ZDB-4-NLEBK
