What do we ask of company members? An annual contribution (the amount is customised) and involvement in the well-being of mathematics in the Netherlands. For us as a society, it is important to have company members for at least two reasons. Members of the KWG underline the social importance of our field, something to which we feel a strong need. In addition, the financial resources from company members enable the KWG to consolidate and expand its activities for mathematics Netherlands.
