Completely antisymmetric tensor
WebOver fields of characteristic zero, the graded vector space of all symmetric tensors can be naturally identified with the symmetric algebra on V. A related concept is that of the antisymmetric tensor or alternating form. Symmetric tensors occur widely in engineering, physics and mathematics .

WebFeb 4, 2011 · This defines the exterior derivative of an asymmetric tensor with two lower indices: a, b, and c are cyclically permuted in each term. Hint: The exterior derivative is not in general zero, as bigubau has pointed out. P.S. I was a lot sleepier than I thought when I first posted this, so left out a constant. For T antisymmetric, WebJun 24, 2024 · By contrast, the tensor product of a k-form by an l-form is antisymmetric, separately, in its first k arguments and in its last l arguments, but it is not necessarily completely antisymmetric in its \(k+l\) arguments (except in the case where k or l is zero); nevertheless, from the tensor product of two differential forms one can obtain a ...
Web1The completely antisymmetric symbol, or permutation symbol, ϵ ijk. This is also called the Levi-Civita symbol, named after the Italian mathematician Tullio Levi-Civita (1873-1941). He is known for work in tensor calculus and was the doctoral student of the inventor of tensor calculus, Gregorio Ricci-Curbastro (1853-1925). http://personal.psu.edu/yuz2/m597k/m597kL11.pdf
