or Minkowski Room. The values with the Levi-Civita image are independent of any metric tensor and coordinate procedure. Also, the precise term "image" emphasizes that it's not a tensor because of how it transforms amongst coordinate systems; nevertheless it may be interpreted for a tensor density.

The time period "n-dimensional Levi-Civita symbol" refers to The reality that the number of indices within the symbol n matches the dimensionality on the vector Room in question, which can be Euclidean or non-Euclidean, for instance, R three displaystyle mathbb R ^ 3

then still left facet is zero, and correct facet is likewise zero due to the fact two of its rows are equal. In the same way for j c = j c + 1 displaystyle j_ c =j_ c+one

The Levi-Civita tensor is used in the Einstein subject equations to express the curvature of spacetime concerning the Vitality and momentum of matter and radiation.

In almost any arbitrary curvilinear coordinate procedure as well as while in the absence of the metric on the manifold, the Levi-Civita image as outlined earlier mentioned might be looked upon as a tensor density industry in two various ways.

The true secret defining home of the image is overall antisymmetry while in the indices. When any two indices are interchanged, equal or not, the image is negated:
