On the existence of optimizers for time-frequency concentration problems
Fabio Nicola, José Luis Romero, S. Ivan Trapasso
We consider the problem of the maximum concentration in a fixed measurable subset of the time-frequency space for functions . Th…

On the convergence of a novel family of time slicing approximation operators for Feynman path integrals
S. Ivan Trapasso
In this note we study the properties of a sequence of approximate propagators for the Schrödinger equation, in the spirit of Feynman's path integrals. Precisely, we consider Hamilt…

Generalized moduli of continuity under irregular or random deformations via multiscale analysis
Fabio Nicola, S. Ivan Trapasso
Motivated by the problem of robustness to deformations of the input for deep convolutional neural networks, we identify signal classes which are inherently stable to irregular defo…
