On I-covering images of metric spaces

چکیده
Let I be an ideal on N. A mapping f : X ? Y is called I-covering provided a sequence {yn}n?N I-converging to point y in Y, there {xn}n?N converging x such that ?1(y) and each xn ?1(yn). In this paper we study the spaces with certain I-cs-networks investigate characterization of images metric under mappings, which prompts us discover I-cs -networks. The following main results are obtained: (1) space has -network if only continuous image space. (2) -countable boundary s-image (3) point-countable I-cs-network

A Note on Sequence-covering Images of Metric Spaces
In this brief note, we prove that every space is a sequence-covering image of a topological sum of convergent sequences. As the application of this result, sequence-covering images of locally compact metric spaces (or, locally separable metric spaces, metric spaces) and sequentially-quotient images of a locally compact metric spaces (or, locally separable metric spaces, metric spaces) are equiv...
متن کاملON SEQUENCE-COVERING mssc-IMAGES OF LOCALLY SEPARABLE METRIC SPACES
We characterize sequence-covering (resp., 1-sequence-covering, 2-sequence-covering) mssc-images of locally separable metric spaces by means of σ-locally finite cs-networks (resp., sn-networks, so-networks) consisting of א0-spaces (resp., sn-second countable spaces, so-second countable spaces). As the applications, we get characterizations of certain sequence-covering, quotient mssc-images of lo...
متن کاملCovering compact metric spaces greedily
Abstract. A general greedy approach to construct coverings of compact metric spaces by metric balls is given and analyzed. The analysis is a continuous version of Chvátal’s analysis of the greedy algorithm for the weighted set cover problem. The approach is demonstrated in an exemplary manner to construct efficient coverings of the n-dimensional sphere and n-dimensional Euclidean space to give ...

متن کاملOn Pseudo-sequence-covering Π-images of Locally Separable Metric Spaces
In this paper, we characterize pseudo-sequence-covering π-images of locally separable metric spaces by means of fcs-covers and point-star networks. We also investigate pseudo-sequence-covering π-s-images of locally separable metric spaces.
