CONCEPT IN MATHEMATICS SPECIFIC TO THE FIELD OF SET THEORY
Intersection (sets); Set theoretic intersection; Nullary intersection; Set intersection; Empty intersection; ∩; Set-theoretic intersection; Intersects; ⋂; Intersect (set theory); Intersection sign; Intersection set theory; Set theory intersection
In set theory, the intersection of two sets A and B, denoted by A \cap B, is the set containing all elements of A that also belong to B or equivalently, all elements of B that also belong to A.
Intersection homology
ANALOGUE OF SINGULAR HOMOLOGY ASSOCIATED TO A TOPOLOGICAL PSEUDOMANIFOLD
Intersection cohomology; Small resolution; Middle perversity; Intersection Cohomology
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 over the next few years.
Intersection form of a 4-manifold
SYMMETRIC BILINEAR FORM ON THE MIDDLE DEGREE (CO)HOMOLOGY GROUP OF AN EVEN-DIMENSIONAL MANIFOLD
Intersection form (4-manifold)
In mathematics, the intersection form of an oriented compact 4-manifold is a special symmetric bilinear form on the 2nd (co)homology group of the 4-manifold. It reflects much of the topology of the 4-manifolds, including information on the existence of a smooth structure.

Line–sphere intersection
In analytic geometry, a line and a sphere can intersect in three ways:
- No intersection at all
- Intersection in exactly one point
- Intersection in two points.
Methods for distinguishing these cases, and determining the coordinates for the points in the latter cases, are useful in a number of circumstances. For example, it is a common calculation to perform during ray tracing.
