abstract

We prove that if $f\in L^p(\mathbb{R}^k)$ with $p<(k^2+k+2)/2$ satisfies that $\widehat{f}$ is supported on a small perturbation of the moment curve in $\mathbb{R}^k$, then $f$ is identically zero. This improves the more general result of Agranovsky and Narayanan, and the exponents are sharp in all dimensions. In the process, we develop a mechanism that should lead to further progress on related problems.

  1. Weighted $L^2$ restriction and comparison of nondegeneracy conditions for quadratic manifolds of arbitrary codimensions

    math.CA 2025-06 conditional novelty 8.0 of 10

    The authors give sharp uniform Fourier decay and weighted L2 restriction for all quadratic manifolds, and an almost complete implication diagram among nondegeneracy conditions.

  2. $L^{p}$-integrability of functions with Fourier supports on fractal sets on the moment curve

    math.CA 2024-12 conditional novelty 7.0 of 10

    If a function lies in L^p and its Fourier transform is supported on a small fractal set on the moment curve, then for p up to a sharp threshold (d^2+d+2α)/(2α) for d≥3, and 4/α for d=2, the function is identically zero.
