An introduction to various topics including combinatorial optimisation, enumeration, and set systems.

Discrete mathematics underpins many areas of modern-day science. In MATH320, we explore selected topics in discrete mathematics in greater depth and detail. In particular, we investigate some technical methods that allow for elegant solutions to more advanced enumeration questions, and explore the structural properties of directed graphs and partially-ordered sets (posets).

Topics covered:

Term 1: Combinatorial enumeration:
Binomial identities and direct enumeration. Principle of Inclusion and Exclusion; Generating functions (ordinary and exponential). Lagrange inversion and applications.

Term 2: Directed graphs and posets:
Basic Ramsey theory, theory of directed graphs (structural results, algorithms, algebraic methods, phase transitions) and partially-ordered sets (Möbius inversion, Dilworth Theorem).

Learning Outcomes

  • Understanding of a range of concepts in combinatorics and the ability to express this clearly in your own words.
  • Ability to devise and write up rigorous mathematical proofs of combinatorial results.
  • Ability to apply general theory to particular examples and problems.
    • University Graduate Attributes

      This course will provide students with an opportunity to develop the Graduate Attributes specified below:

      Employable, innovative and enterprising

      Students will develop key skills and attributes sought by employers that can be used in a range of applications.

      Engaged with the community

      Students will have observed and understood a culture within a community by reflecting on their own performance and experiences within that community.
