When I was reading Folland's A course in abstract harmonic analysis, I was told these materials have wonderful applications to number theory. However, I do not see really a lot of examples there.
Can someone give some references on the applications of harmonic analysis to number theory?
I am asking this question because I am trying to figure out what to do in my coming graduate years. I have learnt a lot analysis but I do not really like doing hard analysis all day, so maybe some application of analysis to other parts of mathematics suits me better.
Thanks so much!
