April 12: The last lecture will be on April 15 at 10.15 in 2344.

February 10: The schedule for lectures has been changed to Tuesdays and Mondays, see below.

# Mathematical and numerical techniques for PDE

This course is given at graduate level and corresponds to 10 hp. The goal is to give an overview of important numerical and mathematical concepts related to PDEs, but also to discuss in detail some techniques, such as analysis of boundary conditions in continuous and discrete settings, and how to use linearization to develop a non-linear theory. Some knowledge of function spaces and functional analysis is useful.

There will be 10 lectures, 4 sets of homework problems, and 1 research papers to read and present. The preliminary plan is to have lectures on Fridays 13-15, but if there is a strong wish for something else please let me know, and maybe a different schedule can be determined.
