List of problems for oral examination
Please make individual appointements for exam that will take place on MSTeams. Students have to discuss two out ten above problems.
Each student can propose one problem she/he would like to discuss, and then she/he will be asked to to discuss another problem chosen
by the examiner. Since problems are are rather broad, students are expected to present structured discussion with emphasis on line of thinking,
methodology, physical interpretetion rather than technical details.
