On uniform spaces with invariant nonstandard hulls
Let 〈X,Γ〉 be a uniform space with its uniformity generated by a set of pseudo-metrics Γ . Let the symbol “ ' " denote the usual infinitesimal relation on ∗X , and define a new infinitesimal relation “ ≈ " by writing x ≈ y whenever ∗ρ(x, p) ' ∗ρ(y, p) for each ρ ∈ Γ and each p ∈ X . Let us call a uniform space 〈X,Γ〉 an S-space if the relations ' and ≈ coincide on fin(∗X). In [14], we showed that...

متن کاملComplex spaces and nonstandard schemes
Nonstandard mathematics furnishes a remarkable connexion between analytic and algebraic geometry. We describe this interplay for the most basic notions like complex spaces/algebraic schemes, generic points, differential forms etc. We obtain by this point of view in particular new results on the prime spectrum of a Stein algebra. 2000 Mathematics Subject Classification 32C15, 14A15 (primary); 32...
متن کاملEmbedding measure spaces
For a given measure space $(X,{mathscr B},mu)$ we construct all measure spaces $(Y,{mathscr C},lambda)$ in which $(X,{mathscr B},mu)$ is embeddable. The construction is modeled on the ultrafilter construction of the Stone--v{C}ech compactification of a completely regular topological space. Under certain conditions the construction simplifies. Examples are given when this simplification o...
متن کاملConversion from Nonstandard to Standard Measure Spaces and Applications in Probability Theory
Let (X, 3, v) be an internal measure space in a denumerably comprehensive enlargement. The set X is a standard measure space when equipped with the smallest standard o-algebra % containing the algebra a, where the extended real-valued measure p. on % is generated by the standard part of v. If / is fl-measurable, then its standard part / is jR-measurable on X. If / and p. are finite, then the vi...
