I completed master's of mathematics in Asia in June 2020. I had written to some professors for PhD positions in number theory in December 2019 . One of the professors in France said yes to me but he said that I should look for other sources of funding as his university didn't have PhD funding at that time. So, I began to look for some funding options but I missed applying for a funding opportunity that is open to anyone whose university would be in that region of France. (I came across on it on web at a date after last date).
Then there was a scholarship application from my country and I began applying for it in mid-March of 2020 but for that a confirmation letter from my prospective guide was required that I was selected for the PhD program. When asked for the letter, the professor didn't reply to my emails, but I can understand that happening due to COVID.
So, then I thought that I would apply to Europe again in December and began studying more topics to improve my knowledge and didn't contacted that professor.
Is it common in French universities that a professor says yes for PhD but tells the student to look for funding opportunities by himself?
