Description:  Aims: The aim of this unit is to continue the development of students' mathematical knowledge and skills by introducing concepts and methods used in a mathematical description of the physical world.
Learning Outcomes: After taking this unit the student should be able to:
* derive theorems of analytic functions and use them to evaluate integrals;
* use superposition methods for inhomogeneous ordinary differential equations;
* solve ordinary differential equations using Green functions;
* derive the EulerLagrange equation and solve problems using the calculus of variations.
Skills: Numeracy T/F A, Problem Solving T/F A.
Content: Functions of a complex variable (11 hours): Functions of z, multivalued functions, branch points and branch cuts. Differentiation, analytic functions, CauchyRiemann equations. Complex integration; Cauchy's theorem and integral. Taylor and Laurent expansions. Residue theorem, evaluation of real integrals. KramersKronig relations.
Superposition methods (5 hours): SturmLiouville theory, eigenfunctions and eigenvalues, orthogonality of eigenfunctions. Solution of inhomogeneous equations. Green's functions: eigenfunction expansion; direct method; application to solution of inhomogeneous ordinary differential equations.
Calculus of variations (6 hours): EulerLagrange equation: derivation and examples. Variation subject to constraints: examples.
