Wheel graphs are planar graphs, and have a unique planar embedding. More specifically, every wheel graph is a Halin graph. They are self-dual: the planar dual of any wheel graph is an isomorphic graph. Every maximal planar graph, other than K 4 = W 4, contains as a subgraph either W 5 or W 6.
Domain coloring plot of the function f(x) = (x 2 − 1)(x − 2 − i) 2 / x 2 + 2 + 2i , using the structured color function described below.. In complex analysis, domain coloring or a color wheel graph is a technique for visualizing complex functions by assigning a color to each point of the complex plane.
A diagram of a wheel, as the real projective line with a point at nullity (denoted by ⊥). A wheel is a type of algebra (in the sense of universal algebra) where division is always defined. In particular, division by zero is meaningful. The real numbers can be extended to a wheel, as can any commutative ring.
Rainbow coloring of a wheel graph, with three colors.Every two non-adjacent vertices can be connected by a rainbow path, either directly through the center vertex (bottom left) or by detouring around one triangle to avoid a repeated edge color (bottom right).

You hear it from every corner of the earth when you’re a woman of a certain age. “Lift heavy,” say the experts. “Cardio adds years to your life, but weightlifting adds life to your years.”
For instance, wheel graphs and connected threshold graphs always have a universal vertex. 3. In the logic of graphs, a vertex that is universally quantified in a formula may be called a universal vertex for that formula. unweighted graph A graph whose vertices and edge s have not been assigned weight s; the opposite of a weighted graph. utility ...
