A multiplicative product of distributions and a class of ordinary differential equations with distributional coefficients
Nuno Costa Dias, Joao Nuno Prata
We construct a generalization of the multiplicative product of distributions presented by L. Hörmander in [L. Hörmander, {\it The analysis of linear partial differential operators…
A multiplicative product of distributions and a global formulation of the confined Schrodinger equation
Nuno Costa Dias, Joao Nuno Prata
A concise derivation of a new multiplicative product of Schwartz distributions is presented. The new product is defined in the vector space of piecewise smooth f…
The Narcowich-Wigner spectrum of a pure state
Nuno Costa Dias, Joao Nuno Prata
We completely characterize the Narcowich-Wigner spectrum of Wigner functions associated with pure states.
Weyl-Wigner Formulation of Noncommutative Quantum Mechanics
Catarina Bastos, Orfeu Bertolami, Nuno Costa Dias +1
We address the phase space formulation of a noncommutative extension of quantum mechanics in arbitrary dimension, displaying both spatial and momentum noncommutativity. By resortin…
