Fourier optimization and quadratic forms
Chirre, Andrés; Quesada-Herrera, Oscar (Peer reviewed; Journal article, 2021)We prove several results about integers represented by positive definite quadratic forms, using a Fourier analysis approach. In particular, for an integer ℓ≥1, we improve the error term in the partial sums of the number ... -
