I understand that all rank 2 tensors can be decomposed into a symmetric and a skew symmetric part, but I don't really understood(adsbygoogle = window.adsbygoogle || []).push({}); howthis is done. It has something to do with permutations of the indices, I guess, but I never learned anything about what a permutation is. Can anyone explain how one would go about symmetrizing (without assuming I have any knowledge of how to permute something)?
