On Wigdersons' approach to the uncertainty principle

Nuno Costa Dias, Franz Luef, João Nuno Prata

We revisit the uncertainty principle from the point of view suggested by A. Wigderson and Y. Wigderson. This approach is based on a primary uncertainty principle from which one can…

Vibration modes of the Euler-Bernoulli beam equation with singularities

Nuno Costa Dias, Cristina Jorge, João Nuno Prata

We consider the time dependent Euler--Bernoulli beam equation with discontinuous and singular coefficients. Using an extension of the Hörmander product of distributions with non-in…

An existence and uniqueness result about algebras of Schwartz distributions

Nuno Costa Dias, Cristina Jorge, Joao Nuno Prata

We prove that there exists essentially one {\it minimal} differential algebra of distributions $\A$, satisfying all the properties stated in the Schwartz impossibility result [L. S…
