Jump functions of a real interval to a Banach space
En este trabajo se estudia la topología de Redfield (R-topología) en el espacio de las medidas finitas y regulares sobre un espacio topológico numerable en el infinito. Para ello debemos estudiar bajo qué condiciones suficientes se puede asegurar que una medida bivalorada es exactamente una carga puntual. En general esta afirmación no es cierta y de ahí las condiciones restrictivas impuestas sobre el tipo de medidas y sobre la naturaleza del espacio topológico en lo que se refiere a la compacidad.Los...
Let be a completely regular space, a boundedly complete vector lattice,
In this paper the problem of the existence of an inverse (or projective) limit measure of an inverse system of measure spaces is approached by obtaining first a measure on the whole product space .The measure will have many of the properties of a limit measure provided only that the measures possess mild regularity properties.It is shown that can only exist when is itself a “limit” measure in a more general sense, and that must then be the restriction of to the projective limit...
It is proved that if X is infinite-dimensional, then there exists an infinite-dimensional space of X-valued measures which have infinite variation on sets of positive Lebesgue measure. In term of spaceability, it is also shown that , the measures with non-σ-finite variation, contains a closed subspace. Other considerations concern the space of vector measures whose range is neither closed nor convex. All of those results extend in some sense theorems of Muñoz Fernández et al. [Linear Algebra Appl....
A multiresolution analysis is defined in a class of locally compact abelian groups . It is shown that the spaces of integrable functions and the complex Radon measures admit a simple characterization in terms of this multiresolution analysis.
We establish a decomposition of non-negative Radon measures on which extends that obtained by Strichartz [6] in the setting of -dimensional measures. As consequences, we deduce some well-known properties concerning the density of non-negative Radon measures. Furthermore, some properties of non-negative Radon measures having their Riesz potential in a Lebesgue space are obtained.
