Curved Ingham Inequalities for Dispersive Trigonometric Sums

Bernhard H Haak, Philippe Jaming, Ming Wang +1

We study $L^2$ restrictions of dispersive trigonometric sums $$F(t,x)=\sum _{n\in \mathbb{Z}}{c}_n{e}^{2\pi i(|n{|}^{s}t+nx)}$$ to curves in the $(t,x)$-plane. Our main result is a curved analogue…
