WebMar 5, 2024 · Ørsted. In electromagnetism, the electromagnetic tensor or electromagnetic field tensor (sometimes called the field strength tensor, Faraday tensor or Maxwell bivector) is a mathematical object that describes the electromagnetic field in spacetime. The field tensor was first used after the four-dimensional tensor formulation of special ... WebAbstract formulation. Let V be a vector space over a field k.The core of the contraction operation, and the simplest case, is the natural pairing of V with its dual vector space V ∗.The pairing is the linear transformation from the tensor product of these two spaces to the field k: : corresponding to the bilinear form , = where f is in V ∗ and v is in V.

WebIn 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 introduced by W. V. D. Hodge.. … Webthe field tensor is easily expressed in terms of derivatives of the four-potential.
