Spaces Whose Pseudocompact Subspaces Are Closed Subsets
Every first countable pseudocompact Tychonoff space X has the property that every pseudocompact subspace of X is a closed subset of X (denoted herein by “FCC”). We study the property FCC and several closely related ones, and focus on the behavior of extension and other spaces which have one or more of these properties. Characterization, embedding and product theorems are obtained, and some exam...
متن کاملMappings of the Sets of Invariant Subspaces of Null Systems
Let P and P ′ be (2k + 1)-dimensional Pappian projective spaces. Let also f : P → P∗ and f ′ : P ′ → P ′∗ be null systems. Denote by Gk(f) and Gk(f ′) the sets of all invariant k-dimensional subspaces of f and f ′, respectively. In the paper we show that if k ≥ 2 then any mapping of Gk(f) to Gk(f ′) sending base subsets to base subsets is induced by a strong embedding of P to P ′. MSC 2000: 51M...
متن کاملStrategies for Updating Terminology Mappings and Subsets
SNOMED CT® (SCT) is a large, comprehensive medical terminology with many applications in the health care IT sector. SCT is often mapped to existing billing classifications as well as to proprietary terminologies in order to support access to and from SCT from existing applications. Subsets of SCT are used to reduce complexity and size. These subsets can vary from small sets that will be used to...
متن کاملMappings into Hyperbolic Spaces
In this note we state some results on extensions of holomorphic mapings into hyperbolic spaces. A theorem involves extending holomorphic mappings to a domain of holomorphy. An extension problem of holomorphic mappings into a taut complex space was considered by Fujimoto [1]. Another result is that the space of all meromorphic mappings from a complex space X into a hyperbolically imbedded space ...
متن کاملUniqueness of linear factorizations into independent subspaces
Given a random vector X, we address the question of linear separability of X, that is, the task of finding a linear operator W such that we have (S1, . . . ,SM ) = (WX) with statistically independent random vectors Si. As this requirement alone is already fulfilled trivially by X being independent of the empty rest, we require that the components be not further decomposable. We show that if X h...
