Weighted norm inequalities for singular integral operators
(London Mathematical Society, 1994-04)
For a Calderón-Zygmund singular integral operator T, we show that the following weighted inequality holds Z Rn|T f(y)|p w(y)dy ≤ C Z Rn |f(y)| p M[p]+1w(y)dy, where Mk is the Hardy-Littlewood maximal operator M iterated ...

q-Deformed Vibron model for diatomic molecules
(American Physical Society, 1994-08)
A deformed version of the vibron model for diatomic molecules is constructed. Both the O(4) and U(3) dynamical symmetries of the model are rewritten, using the concept of complementary subalgebras, in a more convenient ...

Convergence of weighted sums of random variables and uniform integrability concerning the weights
(Universitat de Barcelona, 1994)
Let {ank}, n, k ∈ N be an array of real constants, and let {Xn} be a sequence of random variables. The concept of {ank}-uniform integrability of {Xn} is defined and two characterizations of this concept are established. ...
