I will soon finish my PhD in arithmetic geometry. My advisor told me that I will have to find my next research topic on my own. How do I do that? (Except for "continue where the PhD thesis ends") Can you give me hints/advice?

You should read literature in the area of your previous research, in search of interesting unsolved problems. Also attend conferences and talk to specialists in your field. When I was on this stage of my career, I found surveys with lists of unsolved problems in my field, and tried to solve them. Now I make such lists myself, to help young researchers, and I suppose they exist in every field of mathematics. You have to read a lot to become an expert in your area.
