WebElektromagnetischer Feldstärketensor. Der elektromagnetische Feldstärketensor (auch Faraday-Tensor oder einfach Feldstärketensor) ist eine physikalische Größe, die in der Elektrodynamik das elektromagnetische Feld als Feld in der Raumzeit beschreibt. Er wurde 1908 von Hermann Minkowski im Rahmen der Relativitätstheorie eingeführt.

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.
