- Concept of ellipticity
- Distributions and their convergence properties
- Multiplication by smooth functions and derivatives of distributions
- Fourier transform of distributions

- Understand the different realizations of differential operators on relevant function spaces
- Understand concepts such as existence uniqueness and regularity of solutions to differential equations within the relevant function spaces
- Determine when a certain solution method applies
- Calculate with distributions (derivatives, multiplication, ...)
- Calculate Fourier transform of distributions, and functions in different function classes
- Know the relations (inclusions) of relevant function spaces
- Solve classical differential equations
- Establish existence, uniqueness and regularity of solutions to certain differential equations

5 hours of lectures and 2 hours of exercises each week for 8 weeks
A knowledge of Banach and Hilbert spaces corresponding to An1
and LIM (alternatively An2 from previous years).
Knowledge of the Fourier transform corresponding to FunkAn is desirable.
Academic qualifications equivalent to a BSc degree is recommended.
