APPLIED MATHEMATICS | FMA022 |

**Aim**

The course treats mathematical concepts and methods for partial differential equations. The intention is to make the student acquainted with the whole chain from the drawing up of a model, the theoretical analysis of the model up to a numerical solution. One aim is also to give the students ability to read and judge mathematical reasoning, to give ability in problem solving and training in accounting of mathematical discussions. The main stress is on calculations with paper and pencil, but also on providing via computer exercises acquaintance with mathematical and numerical software.

*Knowledge and understanding*

For a passing grade the student must

be able to show capability to physical interpretation of mathematical models with different boundary conditions, such as the heat equation, the wave equation and Laplace' or Poisson's equation.

be able to show capability to identify Sturm-Liouville operators and in simple cases to find the corresponding eigenfunctions and eigenvalues.

have some experience and understanding of mathematical and numerical software.

*Skills and abilities*

For a passing grade the student must

be able to show capability to use theoretical tools from areas such as special functions and Fourier and Laplace transforms to solve the three "central" partial differential equations in simple cases.

with proper terminology, in a well structured way and with clear logic be able to explain the solution to a mathematical problem within the course.
