The Origins of OCNMP

The current journal Open Communications in Nonlinear Mathematical Physics (OCNMP) came to life as a consequence of the resignation of the Editor in Chief and the Editorial Board from the Journal of Nonlinear Mathematical Physics (JNMP) in September 2020. Below we give a short historical overview of JNMP and the events that led to these resignations.

JNMP was founded in 1994 by Wilhelm I. Fushchich at the Kiev Institute of Mathematics in Ukraine. The journal was subsequently published by the Institute of Mathematics in Kiev with Wilhelm Fushchich as its Editor in Chief and title owner, whereby Wilhelm Fushchich also fully financed the journal at the time. This arrangement sadly ended with his untimely death in April 1997 and the Fushchich family asked Norbert Euler, an in-law family member, to continuewith this journal. N. Euler agreed to serve as the new Editor in Chief and published the journal at his university, Lulea University of Technology (LTU) in Sweden. During the period 1998 to 2006 the journal was then published free and in open access format on the university platform, while it was also possible to purchase printed copies. Under a new management at LTU, around 2005, the University no longer provided a platform for publishing the journal. Because of this, N. Euler made in 2006 a publishing agreement for JNMP with Atlantis Press, and transferred the formal rights to the journal title for the nominal sum of one Swedish Krona to Atlantis Press.

The agreement between N. Euler and Atlantis Press was to continue publishing JNMP in open access format on the Atlantis platform with a possibility to purchase printed copies, i.e. in the same format as before. Nevertheless in 2008 Atlantis Press entered into an agreement with World Scientific Publishing to jointly publish JNMP under the classical subscription model with an online paywall (that allows access to subscribers only) and printed copies for subscribers only. In 2013 Atlantis Press came to a new agreement with Taylor & Francis to jointly publish JNMP under the so-called hybrid publishing model. This made it possible for authors to publish their papers in open access format if they were willing to pay the Article Processing Charge (APC) but authors also had the possibility to publish free of charge behind a paywall. Almost all authors chose not to pay the APC.

In 2020 Atlantis Press decided to migrate JNMP back to the Atlantis Press platform. The journal would now be published in open access format only with compulsory APC. Since this was against the principles in use since the foundation of JNMP, the Editor in Chief N. Euler and the entire Editorial Board of JNMP resigned.

Under Taylor & Francis the Impact Factor of JNMP had grown to over 1.4. The success of JNMP was mainly due to the high quality reviewing system used by JNMP: the Editorial board consisted of scientific experts who chose the referees and oversaw the reviewing process themselves. Moreover, every editorial board member could make comments and hence contribute to the reviewing process for every paper under review. Needless to say, we of course continue with this reviewing process at OCNMP. Our reviewing process is different from many commercial journals, where editorial staff choose referees on the basis of key-words, which can easily lead to quality problems.

Following the resignations of N. Euler and the Editorial Board from JNMP, they pledged to establishing, as soon as possible, a new journal that would cover the same topics as JNMP, but which would be free from any author fees, free for everyone to read, and not connected to any commercial activity or commercial publisher. The result is the current arXiv overlay journal OCNMP, which follows the so-called Diamond Open Access Model and adheres to the Fair Open Access Principle (see ). Being an Overlay journal, it means that all papers are submitted to OCNMP via the arXiv or Hal, whereby the accepted versions are updated on their original arXiv or Hal pages.
