I would like to know if there is a serious study about how the disruption caused by COVID-19 affected the publication figures of some mathematics journals during 2020 and 2021.
Was a downward trend documented somewhere? I mean, in comparison with the figures in 2018-2019 or another biennia prior to the ghastly 2020-2021.
Please, forgive me if you find the implicit premise in this post altogether wrong.
