MAI0098 Student presentations


The examination consists of two parts, hand-in exercises and oral presentations. The exercises are to be solved individually. Ph.D. students need two oral presentations, undergraduate/M.Sc. students need one or two (check under examination on the course information page).

Plan for 25-minute presentations using OH/computer. A preliminary version of the presentation must be handed in a few days before the time of the presentation.


The first presentation should be before November 13, 2020.


Below follows a list of possible topics. You may also propose other topics. Topics related to your research are especially welcome.


Here is the list of presentations 2017 with times, places and titles of presentations (the list is updated during the course). 


You may check the list of presentations 2010, 2013
and 2015.
