I have again added some new journals to my list of those in Diamond Open Access (plus some with currently a fee waiver) :
- three from Cedram.org :
- a new journal in applied math that looks set to be of the highest quality : SMAI Journal of Computational Mathematics
- a well-established pure math journal that has recently switched to Diamond Open Access : Annales de l’Institut Fourier
- another journal that seems completely open too is PMB Algèbre et Théorie des Nombres from the university of Besançon
- two from MSP which I had overlooked :
Still on that topic, it is noticeable that Forum of Mathematics, Pi (which has currently a fee waiver but is not Diamond Access) has published only 7 papers in the space of 3 years : even if it is selecting the very top submissions and routing the rest to Forum of Mathematics, Sigma that’s still much less than the non-Diamond-too but much older Annals of Mathematics or Journal of the AMS.
So, just perhaps, FMP might need to become Diamond to actually make a challenge in the top notch category.
