WebMar 24, 2024 · Tensor notation can provide a very concise way of writing vector and more general identities. For example, in tensor notation, the dot product is simply written (3) where repeated indices are summed over ( Einstein summation ). Similarly, the cross product can be concisely written as (4) where is the permutation tensor . http://dslavsk.sites.luc.edu/courses/phys301/classnotes/summation-notation.pdf edinburgh blood donor centre edinburgh edh https://riflessiacconciature.com
