Coloring Maps of Period Three
All spaces are assumed to be separable metric and all mappings are assumed to be continuous. Definition 1. Suppose that f : X → X is a map from X to itself. An open subset B of X is called a color of (X, f) if f(B) ∩ B = ∅ or, equivalently, f−1(B) ∩ B = ∅. A coloring of (X, f) is a finite cover B of X consisting of colors. The minimal cardinality of a coloring B is called the color number col(X...
متن کاملColoring Maps and the Kowalski Doctrine
It is attractive to regard an algorithm as composed of the logic determining what the results are and the control determining how the result is obtained. Logic programmers like to regard programming as controlled deduction, and there have been several proposals for controlling the deduction expressed by a Prolog program and not always using Prolog’s normal backtracking algorithm. The present no...
متن کاملA SKOS-based multilingual thesaurus of geological time scale for interoperability of online geological maps
The usefulness of online geological maps is hindered by linguistic barriers. Multilingual geoscience thesauri alleviate linguistic barriers of geological maps. However, the benefits of multilingual geoscience thesauri for online geological maps are less studied. In this regard, we developed a multilingual thesaurus of geological time scale (GTS) to alleviate linguistic barriers of GTS records a...

متن کاملColoring of the Self - Organising Maps based on class labels
The Self-Organizing Map (SOM) is a useful and strong tool for data analysis, especially for large data sets or data sets of high dimensionality. SOM visualizations map the data model dimensions to visual dimensions like color and position, thus they help exploring the SOM. Visualization can also involve the data itself so that it helps accessing information that are not available in the trained...
