Additional funding for PhD students Are there 'additional' grants/fellowships available for Mathematics PhD students (who already have their funded positions) in Europe? In other words, does any program analogous to the ERC Starting Grants exist for PhD students?
As for a EU-wide database of research funding opportunities, see EURAXESS:

Go to EURAXESS Funding Search.
Select your RESEARCH FIELD (probably &quot;Formal Sciences&quot;).
Select your FUNDING TYPE (&quot;Funding&quot;? &quot;Mobility Incoming/Outgoing&quot;? &quot;Travel Grants&quot;?).
Select your CAREER STAGE (probably &quot;First Stage Researcher&quot; up to the point of PhD).
Click on Search and browse through the results!

Other than that, there are also national databases. If you tell us the country of your affiliation, perhaps we could link to it. (E.g. https://grants.at/ for Austria.)
