Query: Moment inequalities for trigonometric polynomials with spectrum in
  curved hypersurfaces   Using the multilinear theory of oscillatory integral operators, we establish
a square function inequality with implications to moment inequalities for
discrete exponential sums which frequencies lie on curved hyper-surfaces. In
particular a new distributional estimate for toral eigenfunctions is
established.
