From Infogalactic: the planetary knowledge core. navigation search. In mathematics, the Hodge star operator or Hodge dual is an important linear map introduced in general by W. V. D. Hodge. It is defined on the exterior algebra of a finite-dimensional oriented inner product space.

Nettet14. jun. 2024 · The first excerpt you give talks about the Hodge star for an abstract vector space V which has a metric, i.e. a bilinear function V × V → R. For the second excerpt, you set V = T ∗ pM for a point p in a Riemannian manifold M. Thus the elements of V are dx, dy, dz, etc. Then, as your second question asks, you need a metric on the cotangent ...

A tensor with lowered indices is just the same tensor with lowered indices, and it is definitely not the same as the [Hodge dual][1], which is what you get when you contract with the Levi-Civita tensor, and is the correct definition of the … Nettet29. mai 2024 · (Redirected from Hodge dual) 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.
