Combinatorics is an area of mathematics primarily concerned with counting, both as a means and as an end to obtaining results, and certain properties of finite structures.It is closely related to many other areas of mathematics and has many applications ranging from logic to statistical physics and from evolutionary biology to computer science.
Combinatorics on words is a fairly new field of mathematics, branching from combinatorics, which focuses on the study of words and formal languages. The subject looks at letters or symbols, and the sequences they form. Combinatorics on words affects various areas of mathematical study, including algebra and computer science. There have been a ...
Combinatory logic is a notation to eliminate the need for quantified variables in mathematical logic.It was introduced by Moses Schönfinkel [1] and Haskell Curry, [2] and has more recently been used in computer science as a theoretical model of computation and also as a basis for the design of functional programming languages.
It covers most notably his theory of permutations and combinations; the standard foundations of combinatorics today and subsets of the foundational problems today known as the twelvefold way. It also discusses the motivation and applications of a sequence of numbers more closely related to number theory than probability; these Bernoulli numbers ...
Pingala is credited with being the first to express the combinatorics of Sanskrit metre, eg. [9] Create a syllable list x comprising one light (L) and heavy (G) syllable: Repeat till list x contains only words of the desired length n. Replicate list x as lists a and b. Append syllable L to each element of list a; Append syllable G to each ...
Combinatorics has always played an important role in quantum field theory and statistical physics. [3] However, combinatorial physics only emerged as a specific field after a seminal work by Alain Connes and Dirk Kreimer , [ 4 ] showing that the renormalization of Feynman diagrams can be described by a Hopf algebra .

In 2009, Philippe Flajolet and Robert Sedgewick wrote the book Analytic Combinatorics, which presents analytic combinatorics with their viewpoint and notation. Some of the earliest work on multivariate generating functions started in the 1970s using probabilistic methods. [11] [12] Development of further multivariate techniques started in the ...
