Global and local maximizers for some Fourier extension estimates on the sphere
Valentina Ciccone, Mateus Sousa
In this note, we study maximizers for Fourier extension inequalities on the sphere. We prove that constant functions are local maximizers for the to $L^p(\m…

On Pauli pairs and Fourier uniqueness problems
João P. G. Ramos, Mateus Sousa
We investigate the concept of Pauli pairs and a discrete counterpart to it. In particular, we make substantial progress on the question of when a discrete Pauli pair is automatical…
