thanks for the effort. It is obvious that reading someone’s mind is difficult if not impossible. But still, I found the answer on imechanica forum. Prof. Sia Nemat-Nasser clearly confirms my understanding of the topic. Here is the link to the post http://imechanica.org/node/4356. I recommend...
the coordinates can be covariant or contravariant if the basis is chosen to be contravariant or covariant. The are also cases when tensor is represented in mixed coordinates, i.e. as a linear combination of base vectors, some from tangent space and some from its dual space. So I don't understand...
I often meet the question whether the (physical) space is 'covariant' or 'contravariant'.
I once replied to that question with: Space is space. The COMPONENTS of a tensor are covariant/contravariant if the basis is CHOSEN TO BE contravariant/covariant. As far as I know tensors the...
