Sato-Tate Conjecture

Definition

The Sato-Tate Conjecture is a significant hypothesis in number theory that predicts the distribution of the normalized Frobenius traces of elliptic curves over finite fields. Specifically, it asserts that these traces will be distributed according to a particular probability measure on the unit circle. This conjecture connects deeply with topics such as L-functions, Galois representations, and the Langlands program, reflecting recent advances and ongoing inquiries in analytic number theory.
