Mean-Dispersion Principles and the Wigner Transform

Boiti, Chiara; Jornet Casanova, David; Oliaro, Alessandro (Springer-Verlag, 2024-04-06)

[EN] Given a function f E L2, we consider means and variances associated to f and its Fourier transform , and explore their relations with the Wigner transform W(f), obtaining, as particular cases, a simple new proof of ...
Real Paley-Wiener theorems in spaces of ultradifferentiable functions

Boiti, Chiara; Jornet Casanova, David; Oliaro, Alessandro (Elsevier, 2020-03-01)

[EN] We develop real Paley-Wiener theorems for classes S-omega of ultradifferentiable functions and related L-p-spaces in the spirit of Bang and Andersen for the Schwartz class. We introduce results of this type for the ...
Regularity of partial differential operators in ultradifferentiable spaces and Wigner type transforms

Boiti, Chiara; Jornet Casanova, David; Oliaro, Alessandro (Elsevier, 2017)

[EN] We study the behaviour of linear partial differential operators with polynomial coefficients via a Wigner type transform. In particular, we obtain some results of regularity in the Schwartz space $\Sch$ and in the ...
