Hausdorff Measures of Noncompactness and Interpolation Spaces

da Silva, Eduardo Brandani, Fernanadez, Dicesar L. (2006)

Serdica Mathematical Journal

2000 Mathematics Subject Classification: 46B50, 46B70, 46G12.A new measure of noncompactness on Banach spaces is defined from the Hausdorff measure of noncompactness, giving a quantitative version of a classical result by R. S. Phillips. From the main result, classical results are obtained now as corollaries and we have an application to interpolation theory of Banach spaces.

Infinitely divisible cylindrical measures on Banach spaces

Markus Riedle (2011)

Studia Mathematica

In this work infinitely divisible cylindrical probability measures on arbitrary Banach spaces are introduced. The class of infinitely divisible cylindrical probability measures is described in terms of their characteristics, a characterisation which is not known in general for infinitely divisible Radon measures on Banach spaces. Further properties of infinitely divisible cylindrical measures such as continuity are derived. Moreover, the classification result enables us to deduce new results on...

Integrals and Banach spaces for finite order distributions

Erik Talvila (2012)

Czechoslovak Mathematical Journal

Let c denote the real-valued functions continuous on the extended real line and vanishing at - . Let r denote the functions that are left continuous, have a right limit at each point and vanish at - . Define 𝒜 c n to be the space of tempered distributions that are the n th distributional derivative of a unique function in c . Similarly with 𝒜 r n from r . A type of integral is defined on distributions in 𝒜 c n and 𝒜 r n . The multipliers are iterated integrals of functions of bounded variation. For each n , the spaces...

Isoperimetric problem for uniform enlargement

S. Bobkov (1997)

Studia Mathematica

We consider an isoperimetric problem for product measures with respect to the uniform enlargement of sets. As an example, we find (asymptotically) extremal sets for the infinite product of the exponential measure.

La théorie des cônes biréticulés

Alain Goullet de Rugy (1971)

Annales de l'institut Fourier

Soient 𝒮 la classe des cônes convexes saillants faiblement complets et 𝒮 loc la sous-classe de 𝒮 formée des cônes localement compacts de 𝒮 . Dans les dix dernières années, Alfsen, Bauer, Effros, Rogalski et Stormer ont donné de nombreuses propriétés équivalentes entre elles et qui caractérisent dans 𝒮 loc les cônes de Radon 𝔐 + ( T ) des mesures de Radon positives sur un espace compact T . On montre ici que ces propriétés, convenablement interprétées, restent équivalentes dans la sous-classe 𝒮 p b c des cônes presque bien...

Moments of vector measures and Pettis integrable functions

Miloslav Duchoň (2011)

Czechoslovak Mathematical Journal

Conditions, under which the elements of a locally convex vector space are the moments of a regular vector-valued measure and of a Pettis integrable function, both with values in a locally convex vector space, are investigated.

On an Invariant Borel Measure in Hilbert Space

G. Pantsulaia (2004)

Bulletin of the Polish Academy of Sciences. Mathematics

An example of a nonzero σ-finite Borel measure μ with everywhere dense linear manifold μ of admissible (in the sense of invariance) translation vectors is constructed in the Hilbert space ℓ₂ such that μ and any shift μ ( a ) of μ by a vector a μ are neither equivalent nor orthogonal. This extends a result established in [7].
