Additive Combinatorics ( Winter 2010 )

For A,B subsets of an additive group Z, we define A + B to be the sumset {a + b : a ∈ A, b ∈ B}, and kA to be the k-fold sum A + A + · · · + A of A. We also let A−B = {a−b : a ∈ A, b ∈ B} and b+A = {b}+A for a single element set {b}, a translate of A. Note that A − A is not 0 unless |A| = 1. We let k ¦ A = {ka : a ∈ A}, a dilate of A. There are many obvious properties of “+” that can be checked...

Colloquium on Combinatorics November 12 - 13 , 2010 , Saarbrücken , Germany

s of Invited Talks Dominique Foata (Strasbourg) [Friday, November 12, 09:30 10:30, Room HS 02] Descents and Decreases, Rises and Increases There have been several successful attempts to construct a noncommutative version or a q-analog of the celebrated MacMahon Master Theorem. However those q-analogs sitting in noncommutative algebras remain so far noninstrumental in word enumeration. Another a...

Combinatorics Enumerative Combinatorics 05

Analytic Combinatorics — Symbolic Combinatorics

This booklet develops in nearly 200 pages the basics of combinatorial enumeration through an approach that revolves around generating functions. The major objects of interest here are words, trees, graphs, and permutations, which surface recurrently in all areas of discrete mathematics. The text presents the core of the theory with chapters on unlabelled enumeration and ordinary generating func...
