Popis
Shrnutí:This appendix collects together a number of useful results of vectorial calculus. It shows how to represent vector products using determinants, how to write products of Levy‐Civita tensors in terms of Kronecker deltas. Another tool discussed here is Feynman's technique for manipulating vector expressions involving the Del operator. The appendix closes with a brief discussion of some vector integral theorems.
