Syllabus
Linear algebra: Vector spaces, linear independence and dependence, bases and dimension, rank and nullity of a matrix. Linear mappings, their rank and nullity, their matrix representation, and change of basis. Eigenvalues and eigenvectors. Diagonalisation of matrices, with applications to systems of difference and differential equations (including stabililty). Quadratic forms and orthogonal diagonalisation. Inner product spaces, norms, orthogonality and orthonormalisation.
Functions and mathematical analysis: Sets and functions. Supremum and infinum of bounded sets. Limits of sequences in R and Rm. Limits and continuity of functions. Open subsets and closed subsets of Rm. Compact subsets of Rm. Convex sets, convex and concave funstions. Gradients and directional derivatives. The Jacobian derivative. The Edgeworth Box and contract curves.
Optimisation: Inconstrained optimisation and the second-order conditions. Constrained optimisation and the Kuhn-Tucker theorem. Envelope Theorems. Theory of linear programming
(computational methods will not be included). Duality, with applications. Basic Game Theory.
Note: Students will be expected to work with formal definitions and be able to prove results as well as apply techniques and methods.
