Abstract

For a sequence (a_n)_(n⩾1) of arithmetic interest, it is often desirable to have estimates for the L^p norms of the exponential sum M(α) = Σ_(n⩽X) a_ne(nα) as X grows. Such estimates are useful in applications of the circle method. In addition, sufficiently strong estimates for them can yield estimates for the distribution function {α ∈ [0,1] : |M(α)|⩾ λ} for λ in appropriate ranges.
