Learning Outcomes

On successful completion of this module students should be able to:

Construct various integral transforms and be able to define Fourier, Laplace and Mellin transforms

State the main properties of these three transforms and evaluate their inverses

Make use of the transforms to solve linear ODEs and PDEs

Brief description

In their original formulation, many problems in mathematics appear intractable. The application of an integral transform to an equation often acts to simplify its solution. This module will explain the basic ideas behind integral transforms, generalizing the idea of Fourier transforms to include Laplace and Mellin transforms. Their use will be demonstrated in the solution of both ordinary and partial differential equations. The idea of generalized functions will be introduced, and their properties and applications described.

Content

• Brief description of complex integration: Cauchy's theorem, the residue theorem. Principal value integrals. Computations of standard integrals using contour integrals.
• Distributions and the Dirac delta function.
• The Fourier transform. Linearity, dilation, translation, convolution, derivatives, the inversion formula.
• The Laplace transform. Linearity, dilation, convolution, derivatives, the inversion formula.
• The Mellin transform. Linearity, dilation, convolution, derivatives, the inversion formula.
• Applications of integral transforms to (partial) differential equations, integral equations, difference equations, solid and fluid mechanics.
