{"product_id":"modular-functions-in-analytic-number-theory","title":"Modular Functions in Analytic Number Theory","description":"Knopp's engaging book presents an introduction to modular functions in number theory by concentrating on two modular functions, $\\eta(\\tau)$ and $\\vartheta(\\tau)$, and their applications to two number-theoretic functions, $p(n)$ and $r_s(n)$. They are well chosen, as at the heart of these particular applications to the treatment of these specific number-theoretic functions lies the general theory of automorphic functions, a theory of far-reaching significance with important connections to a great many fields of mathematics.  The book is essentially self-contained, assuming only a good first-year course in analysis. The excellent exposition presents the beautiful interplay between modular forms and number theory, making the book an excellent introduction to analytic number theory for a beginning graduate student.
