Symmetries and Breaking of Symmetries
2016Symmetries help to reduce complexity of calculations. A familiar example is the use of spherical polar coordinates in calculating integrals of quantities which are spherical symmetric. If one manages to find coordinates fitting to symmetries, some of them disappear from the invariant functions and this reduces the calculation task drastically. The same

Skew-Symmetry and Symmetry in the Tensor Algebra
1967Let E be a vector space and let ⊗ p E be a p-th tensorial power of E, p ≧ 2. Then every permutation σ∈SP*) determines a linear automorphism (also denoted by σ) of ⊗ p E given by $$ \sigma ({x_1} \otimes \cdot \cdot \cdot \otimes {x_p}) = {x_{\sigma {}^{ - 1}(1)}} \otimes \cdot \cdot \cdot \otimes {x_{\sigma {}^{ - 1}(p)}}. $$
