2003-2-13 · formal tensor analysis such devices as the parallelogram rule are generally not considered. Two vectors U and V can also be combined via an inner product to form a new scalar η. Thus U · V = η. Example The inner product of force and velocity gives the scalar power being delivered into (or being taken out of) a system f(nt) · v(m/s) = p(W).
2010-1-23 · This is incorrect. His example is not an example of reversing the order of multiplication of two matrices. See my #2.

2019-3-26 · the multiplication is carried out giving the same answer as in equation (2). Note The number of indices indicates the order of the tensor. The scalar (c) does not have an index indicating that it is a 0th order tensor. The vector (a) has one index (i) indicating that it is a 1st order tensor. This is trivial for this case but becomes

2020-11-3 · The equality in the last part of your question is true. One can prove it easier if we look at a matrix as a linear map and look at a matrix product as a composition of linear maps. Furthermore we consider the equality. T ⊗ S ( v ⊗ w) = T ( v) ⊗ S ( w) which is an obvious definition of tensor product of two linear maps. So your equality
