The summer school aims to gather young researchers and to give a motivating goal along which the participants will be able to aggregate new knowledge. The research topics include function field arithmetic, algebraic curves over finite fields, complex multiplication, boolean functions, finite geometry, and combinatorics. The school will be mostly structured into working sessions in small groups under the direction of at least one lecturer. Before the beginning of the school, the lecturers will propose open problems together with pre-request material (books/papers).
