 The Sato-Tate conjecture SMC ColloquiumWednesday 03 November 2010 from 16:00 to 17:00at Room 14
 Speaker : Torsten Ekedahl (SU) Abstract : The Sato-Tate conjecture is an equidistribution conjecture for certain number-theoretically defined sequences. An example of a (generalised) Sato-Tate conjecture is obtained by defining $$\sum_{n=1}^\infty \tau(n) = q\prod_{i=1}^\infty(1-q^n)^{24}.$$ The conjecture then says that $\{\tau(n)/(2n^{5.5})\}$ is equi-distributed with respect to a specific well-known distribution. This is as well as the original Sato-Tate distribution has now been proved by the combined efforts by a fairly large group of people. I will mainly discuss how one by experimentation and pseudo-probabilistic reasoning can arrive at the Sato-Tate conjecture and then indicate the basic idea for the proof.
