Modular forms

Shimura correspondence

In number theory, the Shimura correspondence is a correspondence between modular forms F of half integral weight k+1/2, and modular forms f of even weight 2k, discovered by Goro Shimura. It has the property that the eigenvalue of a Hecke operator Tn2 on F is equal to the eigenvalue of Tn on f. Let be a holomorphic cusp form with weight and character . For any prime number p, let where 's are the eigenvalues of the Hecke operators determined by p. Using the functional equation of L-function, Shimura showed that is a holomorphic modular function with weight 2k and character . Shimura's proof uses the Rankin-Selberg convolution of with the theta series for various Dirichlet characters then applies Weil's converse theorem. (Wikipedia).
