چکیده

A space $X$ is said to have the set star Hurewicz property if for each nonempty subset $A$ of and sequence $(\mathcal{U}_n: n\in \mathbb{N})$ collections sets open in such that $n\in \mathbb N$, $\overline{A} \subset \cup \mathcal{U}_n$, there a $(\mathcal{V}_n: n \in $n \mathbb{N}$, $\mathcal{V}_n$ finite $\mathcal{U}_n$ $x A$, {\rm St}(\cup\mathcal{V}_n, \mathcal{U}_n)$ all but finitely many $n$. In this paper, we investigate relationships among Hurewicz, strongly other related covering properties study topological these spaces.

HOMOTOPICAL EXCISION, AND HUREWICZ THEOREMS, FOR n-CUBES OF SPACES

where e is induced by the ‘excision’ inclusion. That e is an isomorphism in a range of dimensions is shown by the classical Blakers-Massey triad connectivity theorem: if A, B, and A∩B are connected, {A,B} is an open cover of X and (A, A ∩ B) is p-connected, (B, A ∩ B) is q-connected, then the triad (X; A,B) is (p + q)-connected. (See, for example, [11, p. 211].) Further, if p, q > 2 and π1(A∩B)...

Lindelöf Spaces Which Are Menger, Hurewicz, Alster, Productive, or D

We discuss relationships in Lindelöf spaces among the properties “Menger”, “Hurewicz”, “Alster”, “productive”, and “D”. This note is a continuation of [13]. The question of what additional assumptions ensure that the product of two Lindelöf spaces is Lindelöf is natural and well-studied. See e.g., [28], [30], [2], [3], [4], [5], [6], [32], [33]. D-spaces were introduced in [20]. Definition. A s...

some properties of fuzzy hilbert spaces and norm of operators

in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...

The Hurewicz Theorem

The fundamental group and homology groups both give extremely useful information, particularly about path-connected spaces. Both can be considered as functors, so we can use these constructional invariants as convenient guides to classifying spaces. However, though homology groups are often easy to compute, the fundamental group sometimes is not. In fact, it is often not even obvious when a spa...

Comparison of Two Weak Versions of the Orlicz Spaces

In this work two versions of weak Orlicz spaces that appear in the literature, MA and MA, are analyzed. One of those include the weak Lebesgue spaces for 1 :5 p < 00, while the other version gives these spaces only for p > 1, resulting the stronger space L1 in the extrem case p = 1. Necessary and sufficient condit.ions about t.he growth function A in order that. both spaces coincide arc given. ...
