Multiplicative functions | Modular forms | Zeta and L-functions
The Ramanujan tau function, studied by Ramanujan, is the function defined by the following identity: where q = exp(2πiz) with Im z > 0, is the Euler function, η is the Dedekind eta function, and the function Δ(z) is a holomorphic cusp form of weight 12 and level 1, known as the discriminant modular form (some authors, notably Apostol, write instead of ). It appears in connection to an "error term" involved in counting the number of ways of expressing an integer as a sum of 24 squares. A formula due to Ian G. Macdonald was given in . (Wikipedia).
Bertrand Eynard: Integrable systems and spectral curves
Usually one defines a Tau function Tau(t_1,t_2,...) as a function of a family of times having to obey some equations, like Miwa-Jimbo equations, or Hirota equations. Here we shall view times as local coordinates in the moduli-space of spectral curves, and define the Tau-function of a spect

Modular forms: Hecke operators for forms
This lecture is part of an online graduate course on modular forms. We extend Hecke operators from modular functions to modular forms. As an application we prove some of Ramanujan's conjectures for the Ramanujan tau function. For the other lectures in the course see https://www.youtube.c
