Stability for Strichartz inequalities: Existence of minimizers

Boning Di, Dunyan Yan

We study the quantitative stability associated with the adjoint Fourier restriction inequality, focusing on the paraboloid and two-dimensional sphere cases. We show that these Stri…

On $L^{p}$ extremals for Fourier extension estimate to fractional surface

Boning Di, Ning Liu, Dunyan Yan

This article investigates the Fourier extension operator associated with the fractional surface $(ξ, ∣ ξ ∣^{α})$ for $α \geq 2$ . We show that the relevant $L^{p} \to L^{q}$ Fourier extension…
