Functional Analysis uses concepts of the basic Linear Algebra courses such as vector space, linear operator, dual space, scalar product, adjoint map, eigenvalue, spectrum, in order to solve equations in infinite-dimensional function spaces, in particular linear differential equations.
The algebraic notations have to be extended by topological concepts such as convergence, completeness and compactness. This approach was only developed at the beginning of the 20th century, but nowadays it belongs to the methodological basis in Analysis, Numerics and Mathematical Physics, especially in Quantum Mechanics.

We will focus on the aspects of the theory which are relevant for the theory of Partial Differential Equations.

Exercise Sheets
There will be one exercise sheet every week with three or four problems. You can hand in your solution of the two exercises which are labeled with a 'C' and then the tutor will correct it.
In the problem class we will discuss the solutions. If I have not enough time, I will upload my sketches to the missing problems here on the webpage.
