Abstract: Lectures on Tate’s thesis
In the early 20th century, Hecke defined L-functions over number fields which were generalizations of Dirichlet L-functions and he also showed that these Hecke L-functions satisfy a functional equation. John Tate in his seminal thesis gave an elegant treatment of the func- tional equations of the Hecke L-functions, by using Fourier analytic techniques on Adeles and Ideles, which provided a great advance over the classical techniques used by Hecke. In these lectures we will give an overview of the main ideas in this thesis.
