Pronunciation Noun

**graph** (*plural* graphs)

- (
*applied mathematics, statistics*) 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.*hypo*en

- (
*mathematics*) A set of points constituting a graphical representation of a real function; (*formally*) a set of tuples (x_1, x_2, \ldots, x_m, y)\in\R^{m+1}, where y=f(x_1, x_2, \ldots, x_m) for a given function f: \R^m\rightarrow\R.**1969**[MIT Press], Thomas Walsh, Randell Magee (translators), I. M. Gelfand, E. G. Glagoleva, E. E. Shnol,*Functions and*, 2002, Dover, page 19 ↗,**Graphs**- Let us take any point of the first
**graph**, for example, \textstyle x=\frac 1 2, y=\frac 4 5, that is, the point \textstyle M_1(\frac 1 2,\frac 4 5).

- Let us take any point of the first

- (
*graph theory*) (*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; (*less formally*) a set of*vertices*(or*nodes*) together with a set of*edges*that connect (some of) the vertices.*hypo*en

**graphs**first appeared in the mathematical folklore as puzzles (e.g. Königsberg bridge problem). Later,**graphs**appeared in electrical engineering (Kirchhof's Law), chemistry, psychology and economics before becoming a unified field of study.

**1997**, Fan R. K. Chung,*Spectral Graph Theory*, American Mathematical Society, page 1 ↗,- Spectral
**graph**theory has a long history. In the early days, matrix theory and linear algebra were used to analyze adjacency matrices of**graphs**. Algebraic methods are especially effective in treating**graphs**which are regular and symmetric.

- (
*topology*) 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*.- Synonyms: topological graph

\Delta is a 1-dimensional stratified topological space with finitely many 0-strata (vertices) and finitely many 1-strata (edges).

- (
*category theory, of a morphism f*) A morphism \Gamma_f from the domain of f to the product of the domain and codomain of f, such that the first projection applied to \Gamma_f equals the identity of the domain, and the second projection applied to \Gamma_f is equal to f. - (
*linguistics, typography*) 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.- Synonyms: glyph
