symmetric tensor

Définition(s)

In mathematics, a symmetric tensor is a tensor that is invariant under a permutation of its vector arguments:

${\\displaystyle T(v_{1},v_{2},\\ldots ,v_{r})=T(v_{\\sigma 1},v_{\\sigma 2},\\ldots ,v_{\\sigma r})}$

for every permutation σ of the symbols {1, 2, ..., r}. Alternatively, a symmetric tensor of order r represented in coordinates as a quantity with r indices satisfies

${\\displaystyle T_{i_{1}i_{2}\\cdots i_{r}}=T_{i_{\\sigma 1}i_{\\sigma 2}\\cdots i_{\\sigma r}}.}$
