About: Degenerate bilinear form

An Entity of Type: LanguageUnit106284225, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

In mathematics, specifically linear algebra, a degenerate bilinear form f (x, y ) on a vector space V is a bilinear form such that the map from V to V∗ (the dual space of V ) given by v ↦ (x ↦ f (x, v )) is not an isomorphism. An equivalent definition when V is finite-dimensional is that it has a non-trivial kernel: there exist some non-zero x in V such that for all

  • In mathematics, specifically linear algebra, a degenerate bilinear form f (x, y ) on a vector space V is a bilinear form such that the map from V to V∗ (the dual space of V ) given by v ↦ (x ↦ f (x, v )) is not an isomorphism.

  • 数学、とくに線型代数学において、ベクトル空間 V 上の退化 (degenerate) 双線型形式 f(x, y) とは、V から V*（V の双対空間）への で与えられる写像が同型でないような双線型形式である。V が有限次元のときの同値な定義はそれが非自明な核をもつということである、すなわち次を満たす V の 0 でない元 x が存在する すべての y ∈ V に対して f(x, y) = 0. (ja)
