As an example, consider E = F = Z as Z -modules and the Z -bilinear map B: Z × Z → Z given by multiplication: B ( x, y) = x y. Then if x, y ≠ 0, B ( x, y) ≠ 0, so that x ⊗ y ≠ 0 in Z ⊗ Z Z when x, y ≠ 0. Share Cite Follow can i get a mortgage on my paid off homeWebApr 29, 2024 · Tensor is non-zero.

WebAug 7, 2016 · At a single point, off-diagonal elements of the metric tensor simply say that your coordinate system is not orthogonal. For example, if you use x ^ and x ^ + y ^ as your basis in the plane, the resulting metric has a cross term. Since the metric tensor is symmetric, you can always diagonalize it at a single point, so that's not very interesting. WebFeb 25, 2024 · Hi everyone, I am facing the same problem with my model.
