For the time being we cannot give precise fees for the conference.
As it is yet open whether or not we will be able to host a conference with physical presence including meals and a dinner or have to go for a virtual conference with expenses for the storage and streaming of the videos, any estimation of the mandatory pricing to fund the conference are just guesses.
However we can say that the fees for a physical conference will be in the same range as for SheMet2019, which has been around 600,- &Euro; for 3 full days. The fees for a fully virtual conference are likely to be considerably lower.
In any case, the conference will take place and the proceedings will appear and provide a scopus-visible, citeable publication.
We are looking forward to welcome you at ours.
