We prove that the following statement follows from the Open Colouring Axiom (OCA): if X is locally compact a-compact but not compact and if its Cech-Stone remainder X* is a continuous image of w*,…

The result is that if K is spatial, then C(pt(K), A), pt(K) the points of K, embeds into Hom ($cal F) analogous to the case of C (X, A) embedding into Hom $cal F (Ω(A), Ω (X)).

Two new set operators on the ideal topological spaces G and (A) are introduced, similar to the well know relation of the 2020 Mathematics Subject Classi…cation, which deals with two mathematical structures: ideal I and topology simultaneously.

Graph Based Hybrid Clustering With Unbounded Regions
- H. Su, Hong Zhang
Computer Science
- 2017
An extension of the hybrid clustering approach is proposed for partitioning data with possibly unbounded polygon regions for pattern recognition and classification by using a graph to model the initial manual partition of the dataset.

This paper recursively construct a family of access structures having information ratio n, assuming a well-stated informationtheoretic conjecture is true, and emerges after introducing the notion of convec set for an access structure, a subset of n-dimensional real space.

A network-theoretic approach to hyperspectral image classification
- Ryan H. Lewis, A. Harkin
Computer Science
- 2009
A topological and network-theoretic approach for clustering pixels in hyperspectral image data by considering the spectral distance between pairs of pixels, which effectively models the complex nonlinear structures in the data and it can be exploited to perform clustering by applying a community detection algorithm, such as the method of maximum modularity.
