In mathematics, an incidence structure is an abstract system consisting of two types of objects and a single relationship between these types of objects...

mathematics, an incidence matrix is a logical matrix that shows the relationship between two classes of objects, usually called an incidence relation. If...

In mathematics, incidence geometry is the study of incidence structures. A geometric structure such as the Euclidean plane is a complicated object that...

Incidence list, a concept in graph theory Incidence matrix, a matrix that shows the relationship between two classes of objects Incidence structure,...

polyhedra Incidence structures generalize planes (such as affine, projective, and Möbius planes) as can be seen from their axiomatic definitions. Incidence structures...

parallel class structure of an affine plane of order n may be used to construct a set of n − 1 mutually orthogonal latin squares. Only the incidence relations...

graph or incidence graph is a bipartite graph associated with an incidence structure. From a collection of points and lines in an incidence geometry or...

universal set. Hypergraphs can be viewed as incidence structures. In particular, there is a bipartite "incidence graph" or "Levi graph" corresponding to every...

by playing on an arbitrary incidence structure, where rows are lines and cells are points. Tic-tac-toe's incidence structure consists of nine points, three...

In geometry, an incidence relation is a heterogeneous relation that captures the idea being expressed when phrases such as "a point lies on a line" or...
