Star coloring has been introduced by Grünbaum (1973). The star chromatic number χ s ( G ) {\displaystyle \chi _{s}(G)} of G is the fewest colors needed to star color G . One generalization of star coloring is the closely related concept of acyclic coloring , where it is required that every cycle uses at least three colors, so the two ...

The disk and overlay are adjusted so that the observer's local time of day on the overlay corresponds to that day's date on the star chart disc. The portion of the star chart visible in the window then represents (with a distortion because it is a flat surface representing a spherical volume) the distribution of stars in the sky at that moment ...
A chart pattern or price pattern is a pattern within a chart when prices are graphed. In stock and commodity markets trading, chart pattern studies play a large role during technical analysis. When data is plotted there is usually a pattern which naturally occurs and repeats over a period. Chart patterns are used as either reversal or ...
A determining fact source for drawing star charts is naturally a star table. This is apparent when comparing the imaginative "star maps" of Poeticon Astronomicon – illustrations beside a narrative text from the antiquity – to the star maps of Johann Bayer, based on precise star-position measurements from the Rudolphine Tables by Tycho Brahe.
The pattern is made up of three candles: normally a long bearish candle, followed by a short bullish or bearish doji or a small body candlestick, [1] which is then followed by a long bullish candle. To have a valid Morning Star formation, most traders look for the top of the third candle to be at least halfway up the body of the first candle in ...
In graph theory, a star S k is the complete bipartite graph K 1,k : a tree with one internal node and k leaves (but no internal nodes and k + 1 leaves when k ≤ 1). Alternatively, some authors define S k to be the tree of order k with maximum diameter 2; in which case a star of k > 2 has k − 1 leaves. A star with 3 edges is called a claw.
