In mathematics, an n-sphere or a hypersphere is a topological space that is homeomorphic to a standard n-sphere, which is the set of points in (n + 1)-dimensional Euclidean space that are situated at a constant distance r from a fixed point, called the center. It is the generalization of an … Meer weergeven For any natural number n, an n-sphere of radius r is defined as the set of points in (n + 1)-dimensional Euclidean space that are at distance r from some fixed point c, where r may be any positive real number and where c … Meer weergeven We may define a coordinate system in an n-dimensional Euclidean space which is analogous to the spherical coordinate system defined for 3-dimensional Euclidean … Meer weergeven Uniformly at random on the (n − 1)-sphere To generate uniformly distributed random points on the unit (n − 1)-sphere (that is, the surface of the unit n-ball), Marsaglia (1972) gives the following algorithm. Generate an n-dimensional vector of normal deviates Meer weergeven The octahedral n-sphere is defined similarly to the n-sphere but using the 1-norm Meer weergeven The volume of the unit n-ball is maximal in dimension five, where it begins to decrease, and tends to zero as n tends to infinity. … Meer weergeven Just as a two-dimensional sphere embedded in three dimensions can be mapped onto a two-dimensional plane by a stereographic projection, an n-sphere can be … Meer weergeven 0-sphere The pair of points {±R} with the discrete topology for some R > 0.
