Density theorem for Kleinian groups — In the mathematical theory of Kleinian groups, the density conjecture of Lipman Bers, Dennis Sullivan, and William Thurston, states that every finitely generated Kleinian group is an algebraic limit of geometrically finite Kleinian groups.… … Wikipedia
Chebotarev's density theorem — in algebraic number theory describes statistically the splitting of primes in a given Galois extension K of the field Q of rational numbers. Generally speaking, a prime integer will factor into several ideal primes in the ring of algebraic… … Wikipedia
Lebesgue's density theorem — In mathematics, Lebesgue s density theorem states that for any Lebesgue measurable set A, the density of A is 1 at almost every point in A. Intuitively, this means that the edge of A, the set of points in A whose neighborhood is partially in A… … Wikipedia
Jacobson density theorem — In mathematics, the Jacobson density theorem in ring theory is an important generalization of the Artin Wedderburn theorem. It is named for Nathan Jacobson.It states that given any irreducible module M for a ring R , R is dense in its bicommutant … Wikipedia
Kaplansky density theorem — In the theory of von Neumann algebras, the Kaplansky density theorem states thatif A is a * subalgebra of the algebra B ( H ) of bounded operators on a Hilbert space H , then the strong closure of the unit ball of A in B ( H ) is the unit ball of … Wikipedia
Density (disambiguation) — Density and dense usually refer to a measure of how much of some entity is within a fixed amount of space. Types of density include: In physics, density of mass: Density, mass per volume Area density or surface density, mass over a (two… … Wikipedia
Density matrix — Mixed state redirects here. For the psychiatric condition, see Mixed state (psychiatry). In quantum mechanics, a density matrix is a self adjoint (or Hermitian) positive semidefinite matrix (possibly infinite dimensional) of trace one, that… … Wikipedia

Density on a manifold — In mathematics, and specifically differential geometry, a density is a spatially varying quantity on a differentiable manifold which can be integrated in an intrinsic manner. Abstractly, a density is a section of a certain trivial line bundle,… … Wikipedia
Density-dependent inhibition — In population ecology, density dependent inhibition describes a situation in which population growth is curtailed by crowding, predators and competition. In cell biology, it describes the reduction in cell division. When a cell population reaches … Wikipedia
