Incidence (geometry) — In geometry, the relations of incidence are those such as lies on between points and lines (as in point P lies on line L ), and intersects (as in line L1 intersects line L2 , in three dimensional space). That is, they are the binary relations… … Wikipedia
Incidence geometry (structure) — An incidence geometry is a mathematical structure composed of objects of various types and an incidence relation between them. The number of types of object used in the structure is called the rank of the incidence geometry.Incidence geometries… … Wikipedia
De Bruijn–Erdős theorem (incidence geometry) — See also: De Bruijn–Erdős theorem (graph theory) In incidence geometry, the De Bruijn–Erdős theorem, originally published by Nicolaas Govert de Bruijn and Paul Erdős (1948), states a lower bound on the number of lines determined by n points… … Wikipedia
Incidence — may refer to:* Incidence (epidemiology), a measure of the risk of developing some new condition within a specified period of time * Incidence (geometry), the binary relations describing how subsets meet * Angle of incidence, a measure of… … Wikipedia
Incidence structure — In combinatorial mathematics, an incidence structure is a triple :C=(P,L,I)., where P is a set of points , L is a set of lines and I subseteq P imes L is the incidence relation. The elements of I are called flags. If :(p,ell) in I,we say that… … Wikipedia
Incidence matrix — In mathematics, an incidence matrix is a matrix that shows the relationship between two classes of objects. If the first class is X and the second is Y, the matrix has one row for each element of X and one column for each element of Y. The entry… … Wikipedia

Buekenhout geometry — In mathematics, a Buekenhout geometry or diagram geometry is a generalization of projective space, Tits buildings, and several other geometric structures, introduced by Buekenhout (1979). Definition A Buekenhout geometry consists of a set X whose … Wikipedia

Ordered geometry — is a form of geometry featuring the concept of intermediacy (or betweenness ) but, like projective geometry, omitting the basic notion of measurement. Ordered geometry is a fundamental geometry forming a common framework for affine, Euclidean,… … Wikipedia
