# Hermitian form Aller à Hermitian form – A vector space with a Hermitian form (V, h) is called a Hermitian space. The matrix representation of a complex Hermitian form is a . A Hermitian form is positive definite ( often assumed by default) if for all v∈V. If K = ℝ , then antilinear. Jump to: navigation, search. If δ satisfies some irreducible quadratic equation in a field F, then F (δ) is. This is exactly the same as in the case of bilinear forms. There is one difference though between the Hermitian form and the bilinear form case. We can now define sesquilinear forms and Hermitian forms.

Note that f((17),(17))=0. How can a Hermitian form be positive-definite? One of the two axioms for a Hermitian form is ⟨u,v⟩=¯⟨v,u⟩. For u=v this implies ⟨v,v⟩=¯⟨v .
