A set of vertices (or nodes) connected together by edges; (formally) an ordered pair of sets (V,E), where the elements of V are called vertices or nodes and E is a set of pairs (called edges) of elements of V. See also Graph (discrete mathematics) on Wikipedia.Wikipedia
A topological space which represents some graph (ordered pair of sets) and which is constructed by representing the vertices as points and the edges as copies of the real interval [0,1] (where, for any given edge, 0 and 1 are identified with the points representing the two vertices) and equipping the result with a particular topology called the graph topology.
A graphical unit on the token-level, the abstracted fundamental shape of a character or letter as distinct from its ductus (realization in a particular typeface or handwriting on the instance-level) and as distinct by a grapheme on the type-level by not fundamentally distinguishing meaning.
A data chart (graphical representation of data) intended to illustrate the relationship between a set (or sets) of numbers (quantities, measurements or indicative numbers) and a reference set, whose elements are indexed to those of the former set(s) and may or may not be numbers.
A set of points constituting a graphical representation of a real function; (formally) a set of tuples (x_1,x_2,…,x_m,y)∈ R ᵐ⁺¹, where y=f(x_1,x_2,…,x_m) for a given function f: R ᵐ→ R . See also Graph of a function on Wikipedia.Wikipedia
A morphism 𝛤_f from the domain of f to the product of the domain and codomain of f, such that the first projection applied to 𝛤_f equals the identity of the domain, and the second projection applied to 𝛤_f is equal to f.
To draw a graph of a function.
To draw a graph.
A vertex or a leaf in a graph of a network, or other element in a data structure.
A point along a standing wave where the wave has minimal amplitude.
The point at which the lines of a funicular machine meet from different angular directions; — called also knot.
The point where the orbit of a planet, as viewed from the Sun, intersects the ecliptic. The ascending and descending nodes refer respectively to the points where the planet moves from South to North and N to S; their respective symbols are ☊ and ☋.
A similar point on a surface, where there is more than one tangent-plane.
A hard concretion or incrustation which forms upon bones attacked with rheumatism, gout, or syphilis; sometimes also, a swelling in the neighborhood of a joint.
A hole in the gnomon of a sundial, through which passes the ray of light which marks the hour of the day, the parallels of the Sun's declination, his place in the ecliptic, etc.
The word of interest in a KWIC, surrounded by left and right cotexts.
The knot, intrigue, or plot of a dramatic work.
A region of an electric circuit connected only by (ideal) wires (i.e the voltage between any two points on the same node must be zero).
A knot, knob, protuberance or swelling.
The point at which a curve crosses itself, being a double point of the curve. See crunode and acnode.
A leaf node.
A computer or other device attached to a network.
