The lecture is concerned with Banach and Hilbert spaces as well as linear operators acting on these spaces. Typical examples are spaces of continuous and integrable functions and linear maps, which one defines via integration of such functions. In this way one can formulate integral equations as affine or linear equations on a suitable Banach space, and one can solve them by means of functional analytic methods. This class of problems was in fact the historical starting point for the development of functional analysis around 1900. In the following years it became a fundamental area of modern analysis and its applications in- and outside of mathematics.
A preliminary list of topics:
- basic properties and examples of metric and Banach spaces and of linear operators
- Hilbert spaces (scalar product, orthogonal projection and basis)
- principle of uniform boundedness and open mapping theorem
- dual spaces and Theorem of Hahn-Banach
- weak convergence and Theorem of Banach-Alaouglu
- Fourier transform and applications to partial differential equations
Prerequisites: Analysis 1-3 and Linear Algebra 1+2.
