Student seminar
Goal
This semester the seminar will be organized more along the lines of a reading group: first we discuss a part of the text that we read at home, then someone gives a lecture about what follows. We will repeat this a few times whilst working through Chan's Lectures on orders.
Once this is done we will take a look the special case of (maximal orders) on curves and surfaces. We will discuss Artin's conjecture (which is the analogue of the Enriques--Kodaira classification for smooth projective surfaces) and the notion of weighted noncommutative curves. An important reference will be Artin--de Jong's Stable orders over surfaces.
