The journal has remained fully operational throughout the ongoing crisis.

The Nagoya Mathematical Journal is published quarterly with the cooperation of Nagoya University. Since its inception in 1950, the Nagoya Mathematical Journal has endeavored to publish research papers of the highest quality with appeal to the general mathematical audience.

In 2010 the Nagoya Mathematical Journal will move from an open-access to a subscription model to provide a more sustainable funding source for the journal. Please see the NMJ Subscriptions page for more details about this change.
