Not having → symmetry.

→ asymmetry.

Having → axisymmetry.

A tensor that is the negative of its → transpose. For example, a second-order covariant tensor A_jk if its components satisfy the equality: A_jk = - A_kj. Also called antisymmetric tensor.

→ skew; → symmetric; → tensor.

Tânsor, → tensor; pâd-, → anti-; hamâmun, → symmetric.

A relation between two quantities such that the first is to the second as the second is to the first. In symbols: a R b = b R a. For example, multiplication is an operation with a symmetric relation between the factors: 5 x 3 = 3 x 5.

→ symmetric; → relation.

A tensor that is → invariant under any → permutation of its indices (→ index). In other words, a tensor that equals its → transpose. For example, a second-order → covariant tensor A_jk if its components satisfy the equality: A_jk = A_kj.

→ symmetric; → tensor.

Characterized by or exhibiting → symmetry.

Adj. of → symmetry.
