For example, A=[0 1 0 2;3 0 0 4;0 5 6 0]; B=[0 1 0 2;3 7 0 4;8 5 6 0]. I want to find out the location of nonzero entries in B which correspind to zero entries in A. WebThe Riemann curvature tensor is also the commutator of the covariant derivative of an arbitrary covector with itself:;; =. This formula is often called the Ricci identity. This is the classical method used by Ricci and Levi-Civita to obtain an expression for the Riemann curvature tensor. This identity can be generalized to get the commutators for two …

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.

WebMar 7, 2016 · We can show that an elementary tensor x ⊗ y is nonzero by giving an R -bilinear map B: E × F → M such that B ( x, y) ≠ 0. 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
