- AbstractIn the present paper we establish a connection between the L^2 norm of sums of dilated functions whose Fourier coefficients are of order O(j^{−α}) for some α ∈ (1/2, 1), and the spectral norms of certain greatest common divisor (GCD) matrices. Utilizing recent bounds for these spectral norms, we obtain necessary and sufficient conditions for the convergence in L^2 and for the almost everywhere convergence of series of dilated functions.
