Sur une équation fonctionnelle approchée due à J. R. Wilton
arXiv:1508.02991
Abstract
We give a new proof of an approximate functional equation, due to J. R. Wilton, for a trigonometric sum involving the divisor function. This allows us to improve on Wilton's error term and to give an explicit formula for an unspecified function involved in the functional equation.
