Homogeneous spaces in relativity represent the space part of background metrics for some cosmological models; for example, the three cases of the Friedmann–Lemaître–Robertson–Walker metric may be represented by subsets of the Bianchi I (flat), V (open), VII (flat or open) and IX … Meer weergeven In mathematics, particularly in the theories of Lie groups, algebraic groups and topological groups, a homogeneous space for a group G is a non-empty manifold or topological space X on which G acts transitively. … Meer weergeven From the point of view of the Erlangen program, one may understand that "all points are the same", in the geometry of X. This was true of essentially all geometries proposed before Riemannian geometry, in the middle of the nineteenth century. Thus, for … Meer weergeven For example, in the line geometry case, we can identify H as a 12-dimensional subgroup of the 16-dimensional general linear group, GL(4), defined by conditions on the matrix entries h13 = h14 = h23 = h24 = 0, by looking … Meer weergeven • Erlangen program • Klein geometry • Heap (mathematics) Meer weergeven Let X be a non-empty set and G a group. Then X is called a G-space if it is equipped with an action of G on X. Note that automatically G acts by automorphisms (bijections) … Meer weergeven In general, if X is a homogeneous space of G, and Ho is the stabilizer of some marked point o in X (a choice of origin), the points of X … Meer weergeven The idea of a prehomogeneous vector space was introduced by Mikio Sato. It is a finite-dimensional vector space V with a group action of an algebraic group G, such that there is an orbit of G that is open for the Zariski topology (and so, dense).
