The KWG has different membership rates (per year, you will receive a € 2.50 discount if you opt for direct debit):

• normal members: € 97.50
• reciprocity members (see below): € 77.50
• retired and unemployed members: € 52.50
• Student and PhD student members: € 42.50 (for 4 years at a maximum, first year free)

The KWG offers mathematics students (including teacher trainees) a free one-year membership. This free one-year membership can also be requested in the year after obtaining the degree.

PhD students can also request a one-year free membership. 

The free (PhD) student membership automatically ends after one year.

Each KWG member has the right to nominate a new member once a year, in which case the new member does not pay any membership fee for the first year. The free introductory membership is converted into a regular membership after one year.

The membership starts on the first day of the next quarter after your application is received. Payment is preferably made by direct debit, in which case you receive a € 2.50 discount on the membership fee. You can register directly as a member via the electronic form (in Dutch) or by sending an email (in English) to secretaris@wiskgenoot.nl.


Reciprocity membership

If you are already a member of one of the following sister societies, you can claim a reduced rate of € 77.50.

In the Netherlands:

• Society for Statistics and Operations Research (VVSOR)
• Dutch Society for Mathematics Teachers (NVvW)
• Dutch Society for the Development of Arithmetic and Mathematics Education (NVORWO)

Abroad:

• American Mathematical Society
• Australian Mathematical Society
• Belgian Mathematical Society
• Deutsche Mathematiker-Vereinigung
• Gesellschaft für Angewandte Mathematik und Mechanik
• Indian Mathematical Society
• London Mathematical Society
• Real Sociedad Matematica Española
• Society for Industrial and Applied Mathematics
• Société Mathématique de France
• South African Mathematical Society
  

Vice versa, for all these sister societies, KWG membership leads to a discount on their memberships. The rule is that the discount is given for the society in the country where the member does not live. As a KWG member, for example, you are entitled to a reciprocity discount on your AMS membership fee, provided you do not live in the USA. Vice versa, as an AMS member you can get a reciprocity discount of € 20 on your KWG membership fee, provided you do not live in the Netherlands.

Finally: As a member of the KWG you can become a member of the European Mathematical Society for half the price: € 25 (€ 50 normal).


Journals

Each member receives – if wanted – the quarterly journal Nieuw Archief voor Wiskunde and the electronic news letter of the Royal Dutch Mathematical Society. A postage fee of € 10 will be charged for sending the Nieuw Archief voor Wiskunde abroad.

If you wish, you can also subscribe to the following items via the KWG:

• Pythagoras, a mathematics journal directed towards secondary school students.
• Indagationes Mathematicae, the scientific journal of the KWG at reduced rate.
