Stability of the Faber-Krahn inequality for the Short-time Fourier Transform

Jaime Gómez, André Guerra, João P. G. Ramos +1

We prove a sharp quantitative version of the Faber--Krahn inequality for the short-time Fourier transform (STFT). To do so, we consider a deficit $δ (f; Ω)$ which measures by how muc…

On the necessity of the constant rank condition for $L^{p}$ estimates

André Guerra, Bogdan Raiţă

We consider a generalization of the elliptic $L^{p}$ -estimate suited for linear operators with non-trivial kernels. A classical result of Schulenberger and Wilcox (Ann. Mat. Pura App…
