MA1510: COMBINATORICS (2017-2018)

Last modified: 26 Feb 2018 20:00

Course Overview

Combinatorics is the branch of mathematics concerned with counting. This includes counting structures of a given kind (enumerative combinatorics), deciding when certain criteria can be met, finding "largest", "smallest", or "optimal" objects (extremal combinatorics and combinatorial optimization), and applying algebraic techniques to combinatorial problems (algebraic combinatorics). The course is recommended to students of mathematics and computing science.

Further Information & Notes

Course Aims

The course will develop a collection of techniques to solve existence and counting problems in discrete mathematics. It will touch on applications to other parts of mathematics and computer science.


Learning Objectives
By the conclusion of the course the student should have gained an understanding of basic combinatorial concepts and techniques including induction, permutations, partitions, binomial coefficients, generating functions and graphs. The course will also develop students’ skills of logical reasoning and proofs. Many of the methods encountered will be applicable in later mathematics courses.

Degree Programmes for which this Course is Prescribed
