ACM30120 PDEs for Fin. Maths (online)

Academic Year 2021/2022

The aim of the course is to study the three main types of partial differential equations: parabolic (diffusion equation), elliptic (Laplace equation), and hyperbolic (wave equation), and the techniques of solving these for various initial and boundary value problems on bounded and unbounded domains, using eigenfunction expansions (separation of variables, and elementary Fourier series), integral transform methods (Fourier and Laplace transforms). Applications and examples, such as the solution technique for Black-Scholes option pricing, will be discussed throughout the course.

Learning Outcomes:

Upon completion of this module the student should be able to:
Explain the terms existence, uniqueness and stability for PDEs and how this relates to initial and boundary conditions.
Explain the difference between, and be able to give examples of, Dirichlet and Neumann boundary conditions.
Determine whether a PDE is linear, nonlinear, homogeneous, inhomogeneous for given examples.
Solve first order PDEs using the method of characteristics.
Classify a second order partial differential equation by type (Hyperbolic, Elliptic, Parabolic) and classify it by order or linearity.
Complete (given a partial proof) proofs for uniqueness of solutions for the wave, diffusion and Laplace equations.
Demonstrate the use of energy methods and the maximum principle to determine uniqueness and stability for a given PDE.
Construct finite difference formulations for diffusion equation and Laplace equation and interpret the output of computational simulations in terms of stability and accuracy.
