Isotropic quadratic form — In mathematics, a quadratic form over a field F is said to be isotropic if there is a non zero vector on which it evaluates to zero. Otherwise the quadratic form is anisotropic. More precisely, if q is a quadratic form on a vector space V over F … Wikipedia
Isotropic manifold — In mathematics, an isotropic manifold is a manifold in which the geometry doesn t depend on directions. A homogeneous space is a similar concept. A homogeneous space can be non isotropic, in the sense that an invariant metric tensor on a… … Wikipedia
Isotropic coordinates — In the theory of Lorentzian manifolds, spherically symmetric spacetimes admit a family of nested round spheres . There are several different types of coordinate chart which are adapted to this family of nested spheres; the best known is the… … Wikipedia
Space frame — The roof of this industrial building is supported by a space frame structure. A space frame or space structure is a truss like, lightweight rigid structure constructed from interlocking struts in a geometric pattern. Space frames can be used to… … Wikipedia
Symplectic vector space — In mathematics, a symplectic vector space is a vector space V equipped with a nondegenerate, skew symmetric, bilinear form omega; called the symplectic form. Explicitly, a symplectic form is a bilinear form omega; : V times; V rarr; R which is *… … Wikipedia
Scale space — theory is a framework for multi scale signal representation developed by the computer vision, image processing and signal processing communities with complementary motivations from physics and biological vision. It is a formal theory for handling … Wikipedia

Curved space — often refers to a spatial geometry which is not “flat” where a flat space is described by Euclidean geometry. Curved spaces can generally be described by Riemannian geometry though some simple cases can be described in other ways. Curved spaces… … Wikipedia
Indefinite inner product space — In mathematics, in the field of functional analysis, an indefinite inner product space :(K, langle cdot,,cdot angle, J) is an infinite dimensional complex vector space K equipped with both an indefinite inner product :langle cdot,,cdot angle and… … Wikipedia
Outer space — For other uses, see Outer space (disambiguation). The boundaries between the Earth s surface and outer space, at the Kármán line, 100 km (62 mi) and exosphere at 690 km (430 mi). Not to scale Outer space is the void that exists beyond any… … Wikipedia
