41Intersection theory (mathematics) — In mathematics, intersection theory is a branch of algebraic geometry, where subvarieties are intersected on an algebraic variety, and of algebraic topology, where intersections are computed within the cohomology ring. The theory for varieties is …
42Intersection homology — In topology, a branch of mathematics, intersection homology is an analogue of singular homology especially well suited for the study of singular spaces, discovered by Mark Goresky and Robert MacPherson in the fall of 1974 and developed by them… …
43Intersection number (graph theory) — In the mathematical field of graph theory, the intersection number of a graph is the smallest number of elements in a representation of G as an intersection graph of finite sets. Equivalently, it is the smallest number of cliques needed to cover… …
44Intersection (road) — Crossroad in Kharkov An intersection is a road junction where two or more roads either meet or cross at grade (they are at the same level). An intersection may be 3 way a T junction or fork, 4 way a crossroads, or 5 way or more. It may often be… …
45Intersection graph — In the mathematical area of graph theory, an intersection graph is a graph that represents the pattern of intersections of a family of sets. Any graph may be represented as an intersection graph, but some important special classes of graphs may… …
46Intersection (set theory) — Intersections of the Greek, Latin and Russian alphabet (upper case graphemes) (The intersection of Greek and Latin letters is used for the Greek licence plates.) …

49Intersection number — In mathematics, the concept of intersection number arose in algebraic geometry, where two curves intersecting at a point may be considered to meet twice if they are tangent there. In the sense that multiple intersections are limiting cases of n… …
50Intersection form (4-manifold) — In mathematics, the intersection form of an oriented compact 4 manifold is a special symmetric bilinear form on the 2nd cohomology group of the 4 manifold. It reflects much of the topology of the 4 manifolds, including information on the… …
