Projects

60% of the grade is based on a project. The project (which can be done individually or in groups of two) can be a literature review, but I would recommended attempting to do original research, either by trying to make partial progress on (or completely solve!) one of the open problems below, or by pursuing another research direction. There are forty-two open problems (now 41, as in meanwhile Open Problem 1.3 has been solved [MS15]!).
