In this section, we discuss the gen-eral de nition in Euclidean and Lorentzian vector spaces and give formulae for concrete calculations in (pseudo-)orthonormal frames. NettetThe above expression is, again, slightly misleading, since stands for the component of the pseudo-3-tensor , and not for an element of the proper-3-vector .Of course, in this case, really does represent the first element of the pseudo-3-vector .Note that the elements of are obtained from those of by making the transformation and ..

Hodge theory on Riemannian … NettetIn case n = 4, the Hodge dual acts as an endomorphism of the second exterior power (i.e. it maps two-forms to two-forms, since 4 − 2 = 2). It is an involution, so it splits it into self-dual and anti-self-dual subspaces, on which it acts respectively as +1 and −1.

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
