An extension of J. Palis’ lambda-lemma is obtained for one case of non-transversal intersection of the stable and unstable manifolds of an hyperbolic fixed point of a C2 local diffeomorphism of R2.

Se recuerda la definición del número equivalente, propuesto para medir el número de unidades independientes de información y lo adaptamos al contexto del análisis multivariado de datos. Proponemos algunas propiedades en ...

Using W. Rudin’s method it is shown that the tauberian theorem can be generalized to several kernels other than the Poisson kernel. We also proof an inverse of the tauberian theorem, that is, an abelian theorem.

In this paper we study conditions under which morphims f que va de X a Y, are K-finite in a topos E. We construct some counterexamples.

Este artículo utiliza la técnica de expansión asintótica parcial aplicada a distribuciones de orden finito, con el fin de obtener la expansión distribucional de núcleos de la forma f( /lambda x , y), cuando /lambda  tiende ...

We show that Hill’s equation with white noise potential has a sequence of Dirichlet eigenvalues /lambda n that behaves almost like in the classical case, in the sense that /lambda n - n2/pi 2 has a logarithmic growth coming ...

A partir de resultados obtenidos sobre la representación binaria de los procesos puntuales en tiempo continuo, se obtiene, bajo hipótesis de separabilidad, un análogo en tiempo discreto ( procesos de incrementos casi ...

This is the second of a series of two articles en which we study the Karmarkar’s method. In this article we are going to show how can we use sparse matrix theory to get an efficient implementation of the Karmarkar’s process ...

The quota power of UN Security Council members are analysed from a mathematical point of view, using Game Theory. Results are generalized and applied to the current situation. Some recommendations are stated about the ...
