The authors turn out a common type of the sum formulation SL2 over a wholly actual quantity box. This formulation relates sums of Kloosterman sums to items of Fourier coefficients of automorphic representations. The authors provide models: the spectral sum formulation (in brief: sum formulation) and the Kloosterman sum formulation. they've got the autonomous attempt functionality within the spectral time period, within the sum of Kloosterman sums, respectively
