The resulting ω satisfies your condition but is not self-dual with respect to any metric. (The requirement that n be even is so that α ∧ ∗ α = ∗ α ∧ α. If n is odd, then ω ∧ ω = 0 for ...

In mathematics, the Hodge star operator or Hodge star is a linear map defined on the exterior algebra of a finite-dimensional oriented vector space endowed with a nondegenerate symmetric bilinear form. Applying the operator to an element of the algebra produces the Hodge dual of the element. This map was … Se mer Let V be an n-dimensional oriented vector space with a nondegenerate symmetric bilinear form $${\displaystyle \langle \cdot ,\cdot \rangle }$$, referred to here as an inner product. This induces an inner product Se mer Applying the Hodge star twice leaves a k-vector unchanged except for its sign: for $${\displaystyle \eta \in {\textstyle \bigwedge }^{k}V}$$ in an n-dimensional space V, one has Se mer Two dimensions In two dimensions with the normalized Euclidean metric and orientation given by the ordering (x, y), the Hodge star on k-forms is given by On the complex plane regarded as a real vector space with the … Se mer For an n-dimensional oriented pseudo-Riemannian manifold M, we apply the construction above to each cotangent space $${\displaystyle {\text{T}}_{p}^{*}M}$$ and … Se mer Nettet23. feb. 2024 · How to derive the coordinate expression of the Hodge dual?
