Hodge star operator in nLab - ncatlab.org

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 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 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 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 NettetThese lecture notes in the De Rham–Hodge theory are designed for a 1–semester undergraduate course (in mathematics, physics, engineering, chemistry or biology). … maytag washer parts store near me

Nettetwith the K¨ahler form and its adjoint operation with respect to the Hodge inner product. A more recent result of Verbitsky [5,6] states that if the manifold is hyperK¨ahler, then the so(2,1) action is part of a larger so(4,1) action, which is now generated by exterior products with each of the three K¨ahler forms and their adjoints. Nettet1. jun. 2024 · The Hodge inner product. On smooth manifolds the Hodge star operator together with the wedge product defines the Hodge inner product, our definition is derived in the same fashion. On the contrary, in classical DEC, e.g., (Desbrun et al., 2006), the Hodge star is actually derived from a previously given inner product.

Nettet9. okt. 2024 · The standard way to define inner products on the exterior algebra ∧kV, extending the inner product defined on the underlying vector space V, looks like this: i=1⋀k ai, i=1⋀k bi = det ai,bj . This is then extended linearly if either argument is a sum of multivectors. This expression is pretty confusing. It turns out be the same as (1), but ...

NettetGiven an inner product on V there is a natural inner product on the dual space V: Speci cally, notice that the non-degeneracy of the inner product says that the map C: V !V : v7!hv;i is an isomorphism.

The relationship between the wedge and cross products is given by taking the Hodge star.
