WebThe idea of an n-dimensional Euclidean space for n > 3 appeared in a work on the divergence theorem by the Russian mathematician Michail Ostrogradsky (1801--1862) in 1836, in the geometrical tracts of Hermann Grassmann (1809--1877) in the early 1840s, and in a brief paper of Arthur Cayley (1821--1895) in 1846.

WebGrassmannian is a homogeneous space of the general linear group. General linear group acts transitively on with an isotropy group consisting of automorphisms preserving a given subspace. If the space is equipped with a scalar product (hermitian metric resp.) then the group of isometries acts transitively and the isotropy group of is . WebGrassmann Algebra starts with a vector space (or more generally a module) of dimension 'n' and from it generates a vector space 'A' of dimension 2 n or, another way to think about it, the vector space 'A' is made up of a number of smaller dimensional vector spaces. sumner county election commission tennesseeWebThe notation v 1 ∧ ⋯ ∧ v i should be understood to refer to the parallelotope made from the vectors v 1, ⋯, v i ∈ V. If i < d = dim V then the "volume" of the parallelotope v 1 ∧ ⋯ ∧ v i is always zero; keep in mind the key point that the Grassmann algebra on V is a priori concerned with d -dimensional volume. sumner county election commission gallatin tn
