Some classical problems like the Waring problem on the sum of k-th powers or the Goldbach conjecture are genuine examples of the original questions addressed in the area. One of the features of contemporary

In the setting of Krull monoids (the main examples we have in mind are the multiplicative monoids of rings of integers of algebraic number fields) most problems can be translated into zero-sum problems over the class group. It will be a main aim of this course to highlight this relationship.
