NettetHodge felt that these techniques should be applicable to higher dimensional varieties as well. His colleague Peter Fraser recommended de Rham's thesis to him. In reading de Rham's thesis, Hodge realized that the real and imaginary parts of a holomorphic 1-form on a Riemann surface were in some sense dual to each other. Nettet19. aug. 2024 · $\begingroup$ I don't think what you wrote about the definition of the dual by lowering indices is correct. 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 …

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 NettetHodge felt that these techniques should be applicable to higher dimensional varieties as well.
