I am writing my statement of purpose for a PhD in mathematics for various universities. I know that it is a good thing to motivate why you want to go to that university in particular, but I was wondering at what point one should do this.
What I have for the moment is a paragraph in the end where I explain my reasons for applying, and talk about why I think that university in particular should be fitting for me. Is that enough? Or should there be mentions of the university in the whole statement?
