 asymmetric, asymmetrical   ناهمامون   nâhamâmunFr.: asymétrique   Not having → symmetry. axisymmetric   همامون ِ آسه‌ای، آسه-همامون   hamâmun-e âse-yi, âse-hamâmunFr.: axisymétrique   Having → axisymmetry. skew-symmetric tensor   تانسور ِ پاد-همامون   tânsor-e pâdhamâmunFr.: tenseur antisymétrique   A tensor that is the negative of its → transpose. For example, a second-order covariant tensor Ajk if its components satisfy the equality: Ajk = - Akj. Also called antisymmetric tensor.→ skew; → symmetric; → tensor.Tânsor, → tensor; pâd-, → anti-; hamâmun, → symmetric. symmetric relation   بازانش ِ همامون   bâzâneš-e hamâmunFr.: relation symétrique   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. symmetric tensor   تانسور ِ همامون   tânsor-e hamâmunFr.: tenseur symétrique   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 Ajk if its components satisfy the equality: Ajk = Akj.→ symmetric; → tensor. symmetric, symmetrical   همامون   hamâmunFr.: symétrique   Characterized by or exhibiting → symmetry.Adj. of → symmetry.
