Guth , Alexander Vilenkin (Submitted on 1 Oct 2001 ( v1 ), last revised 14 Jan 2003 (this version, v2)) Combinatorics is a branch of mathematics concerning the study of finite or countable discrete structures. Aspects of combinatorics include counting the structures of a given kind and size 2 Linear recurrences Linear recurrence: Each term of a sequence is a linear function of earlier terms in the sequence. For example: a 0 = 1 a 1 = 6 a 2 = 10 a n = a n-1 + 2a n-2 + 3a n-3 Combinatorics is the study of how to count things. By hings" we mean the various combinations, permutations, subgroups, etc., that can be formed from a given set of objects or events. For example, how many di?erent committees of three people can be chosen from Combinatorics is a branch of mathematics which is about counting - and we will discover many exciting examples of "things" you can count.. First combinatorial problems have been studied by ancient Indian, Arabian and Greek mathematicians.
