Ordinary differential equations with point interactions: An inverse problem
Nuno Costa Dias, Cristina Jorge, Joao Nuno Prata
Given a linear ordinary differential equation (ODE) on $\RE$ and a set of interface conditions at a finite set of points $I \subset \RE$, we consider the problem of determining ano…

What is the Wigner function closest to a given square integrable function?
J. S. Ben-Benjamin, L. Cohen, N. C. Dias +2
We consider an arbitrary square integrable function on the phase space and look for the Wigner function closest to it with respect to the norm. It is well known that the…

Wigner functions on non-standard symplectic vector spaces
Nuno Costa Dias, João Nuno Prata
We consider the Weyl quantization on a flat non-standard symplectic vector space. We focus mainly on the properties of the Wigner functions defined therein. In particular we show t…
