Uniformizable and Realcompact Bornological Universes
Bornological universes were introduced by Hu in [11] and obtained renewed interest in recent articles on convergence in hyperspaces and function spaces and optimization theory. In [11] and [12] Hu gives a necessary and sufficient condition for which a bornological universe is metrizable. In this article we will give a characterization of uniformizable bornological universes. Furthermore, a cons...
متن کاملNearly tight frames of spin wavelets on the sphere
We show that the spin wavelets on the sphere S2, which were constructed by the first author and Marinucci in [3], can be chosen so as to form a nearly tight frame. These spin wavelets can be applied (see [1] and [2]) to the study of the polarization of cosmic microwave background radiation. For certain of these frames, there is a positive C such that each frame element at scale aj is supported ...
متن کاملNearly Tight Frames and Space-Frequency Analysis on Compact Manifolds
Let M be a smooth compact oriented Riemannian manifold, and let ∆ be the Laplace-Beltrami operator on M. Say 0 6= f ∈ S(R), and that f(0) = 0. For t > 0, let Kt(x, y) denote the kernel of f(t∆). Suppose f satisfies Daubechies’ criterion, and b > 0. For each j, write M as a disjoint union of measurable sets Ej,k with diameter at most ba j , and comparable to ba if ba is sufficiently small. Take ...
متن کاملQuotients of Strongly Realcompact Groups
A topological group is strongly realcompact if it is topologically isomorphic to a closed subgroup of a product of separable metrizable groups. We show that if H is an invariant Čech-complete subgroup of an ω-narrow topological group G, then G is strongly realcompact if and only if G/H is strongly realcompact. Our proof of this result is based on a thorough study of the interaction between the ...
متن کاملMaximal Realcompact Spaces and Measurable Cardinals
Comfort and Hager investigate the notion of a maximal realcompact space and ask about the relationship to the first measurable cardinal m. A space is said to be a P (m) space if the intersection of fewer than m open sets is again open. They ask if each realcompact P (m) space is maximal realcompact. We establish that this question is undecidable.
