Student seminar
Goal
The goal would be to familiarise with the classical theory of Chern classes in algebraic geometry using both Fulton's and Grothendieck's approach, discuss interesting examples, and maybe discuss noncommutative generalisations of the theory.
For some references, consider the absolute classic [1] by Fulton, the more accessible notes by Gathmann [2] (chapters 9 and 10) or Teitler [5], the unfinished (but excellent) text book [4] and Grothendieck's article [3].
