APPLIED MATHEMATICS - PARTIAL DIFFERENTIAL EQUATIONS | FMAF15 |

**Aim**

The aim of the course is to treat such mathematical concepts and methods in vector analysis and partial differential equations above the basic level that are important for further studies within e.g. mechanics, solid mechanics, fluid mechanics, ecology, electrical engineering and for further professional activities.

*Knowledge and understanding*

For a passing grade the student must

have a good knowledge of Fourier series and their application for solving model problems in partial differential equations, and have knowledge of the Fourier transform.

be able to show good understanding of concepts such as initial conditions and boundary conditions.

be able to demonstrate an ability to draw up and interpret mathematical models with different boundary conditions for the three basic types of differential equations: the heat/diffusion equation, the wave equation, the Laplace equation.

have some experience and understanding of mathematical and numerical software for differential equations.

*Skills and abilities*

For a passing grade the student must

be able to show an ability to use the concepts introduced in the course in connection with modelling and problem solving.

with proper terminology, suitable notation, in a well-structured manner and with clear logic, be able to explain the solution to a problem.
