Dear Quaternion Community

2020 Joint Mathematics Meeting News

There will be no Quaternion Special Session at the 2020 JMM.  The AMS didn’t approve our 2020 Quaternion Special Session proposal.  Hopefully, we will have a Quaternion Session at the 2021 JMM.

However, the AMS did approve our proposal on Evolution.
