A Method for Estimating the $L_1$ Norm of an Exponential Sum Based on Arithmetic Properties of the Spectrum
S. V. Bochkarev
Abstract:
A new lower estimate of the $L_1$ norm of a general exponential sum is established in terms of the ratios of the $L_p$ ($p>2$) and $L_2$ norms of dyadic blocks. In particular, for sums of exponents with coefficients whose absolute values are 0 and 1, the estimates are found such that the density and arithmetic properties of the spectrum are simultaneously taken into account. The results obtained are unimprovable in a certain sense.
