The Problem Section of the Nieuw Archief

The Problem Section of the Nieuw Archief voor Wiskunde is open to everyone; everybody is encouraged to send in solutions and propose problems. Group contributions are also welcome. The competition is organised under the aegis of the Royal Dutch Mathematical Society.

The prizes

Each session consists of a number of problems of increasing difficulty. For each problem, the most elegant correct solution will be rewarded with a 20 Euro book token.

At times there will be a Star Problem, to which the proposer does not know any solution. The contributor of the first correct solution within one year will receive a prize of 100 Euro.

Submission

Submission by email (in LaTeX) is preferred; participants should repeat their name, address and university at the beginning of each problem/solution. Submissions must be sent to the coordinator of the Problem Section before the submission deadline (see above). The address is:

Problem Section NAW
Mathematisch Instituut, Univ. Leiden
Postbus 9512
2300 RA Leiden
E-mail:

When proposing a problem, please either include a complete solution or else indicate that it is intended as a Star Problem.
