We prove some basic properties of p-bounded subsets (p epsilon omega) in terms of z-ultrafilters and families of continuous functions, We analyze the relations between p-pseudocompactness with other pseudocompact like-properties ...

We relate the properties of the postsingular set for the exponential family regarding stability questions. We calculate the action of the Ruelle operator for the exponential family, and we prove that if the asymptotic (or ...

Abstract Let (B, ∥ · ∥) be a separable Banach space. Let Y, Y1, Y2, ... be centered i.i.d. random vectors taking values on B with law μ, μ(·) = P(Y ∈ ·), and let Sn = Σi=1n Yi. Under suitable conditions it is shown for ...

(2) every class P-P is closed under arbitrary products

Let X be a Hausdorff topological group and G a locally compact subgroup of X. We show that the natural action of G on X is proper in the sense of R. Palais. This is applied to prove that there exists a closed set F subset ...

Let R be an algebra, and let (theta, <=) be a stratifying system of R-modules. If the category) F(theta) is theta-directing, then we prove that ind F(theta) is finite. In order to do that, we introduce a quadratic form ...

Let (B, parallel to . parallel to) be a real separable Banach space of dimension 1 less than or equal to d less than or equal to infinity, and assume X,X-1, X-2,... are i.i.d. B valued random vectors with law mu=L(X) and ...

Ante la ausencia de textos en español, Antonio Minzoni entrega a la comunidad de actuarios, a los interesados en los seguros y muy especialmente, a los estudiantes universitarios, un arma que les será de gran utilidad.

Given a metric continuum X, let 2(X) denote the hyperspace of all nonempty closed subsets of X. For each positive integer k let C-k(X) stand for the hyperspace of members of 2(X) having at most k components. Consider ...
