La ecuación de Navier-Stokes y multifractales
(2009-02-25)
There is currently no general theorem on the existence and unicity of solutions tothe Navier-Stokes equation, which describes the flow of a viscous and incompressiblefluid. This is an open problem at the international ...

Métodos de punto interior para optimización cuadrática convexa con matrices no definidas positivas
(2009-02-25)
In this article a modification of the recursive algorithm of Cholesky is obtainedthat allows the factorization of Semi Definite Positive Matrices, even though theseare not positive defined, without increasing the computational ...
An approach to ladder operators for the two-dimensional harmonic oscillator
An approach to ladder operators for the two-dimensional harmonic oscillator
(2009-02-25)
We show that elementary properties of associated Laguerre polynomials generatethe ladder operators for the harmonic oscillator radial wave function in two dimensions.Keywords: Harmonic oscillator, ladder operators, Laguerre ...
