*Fourier transform and applications*

Parseval formula and inversion formula. Convolution of functions. Applications to the resolution of the heat, wave and Schroedinger equation. Calculation of Fourier transforms with the residue theorem. Gaussian function. Lorentzian function. Voigt function. Distribution of Fourier transforms. Distributions. Definition and simple properties. Approximation of the Dirac delta distribution.

*Special functions*

Functions of Laguerre, Legendre, Bessel. Spherical harmonics.

*Elements of Calculus of Variations*

Functional derivative. Euler-Lagrange equation.

*Laplace transform*

Application of the Laplace transform to the solution of ordinary differential equations with boundary or initial conditions.

### Prerequisites

Basic mathematical analysis: differential calculus for functions of one or several variables, ordinary and partial differential equations, integral calculus.

### Teaching form

Lectures and exercises.

### Textbook and teaching resource

K. F. Riley, M. P. Hobson and S. J. Bence. Mathematical Methods for Physics and Engineering, Cambridge University Press.

Further material will be suggested or distributed during the course.

### Semester

First Semester 2018-19

### Assessment method

Written exam: exercises and problems with open questions.

Oral exam: discussion of the written exam; solution of further exercises can be required; questions on definitions, statements and (selected) proofs of theorems.

It is possible to take the oral exam even if the result of the written exam is not sufficient.

### Office hours
