- Grading MSc students: Assessed based on ca. 4-6 homework assignments; no written exam. UPDATE: All homework problems will count equally. We plan to use the following grading scheme: 90%-100% A, 80%-90% B, 70%-80% C, 60%-70% D, 50%-60% E, <50% F.
- Grading PhD students: Pass/Fail. In addition to homework, PhD students will be asked to make a short oral presentation (ca. 20 minutes) .For the oral presentations by PhD students, an excellent presentation will raise the grade by one letter (e.g. from C up to B), an OK presentation will maintain the same grade and a poor presentation will lower the grade by one letter (A to B, B to C etc.) Tentatively, after the oral presentation, you will need an A or B to pass (meaning that if you have at least a B, you certainly pass; if the grades become very low for some reason, then we may re-evaluate whether C should pass too)

Sections 1-2 give an overview of root data, root systems, reductive groups over algebraically closed fields and their classification in terms of root data. Thus sections 1-2 give a concise summary of the aim of the first half of the course.
