For me, the universal mapping property is the defining characteristic of a tensor product. Though n-dimensional arrays are one way to help grasp tensors, I prefer other definitions because I find them clearer, even if harder to understand. For example, a tensor is entirely independent...

  Understanding tensors as matrices doesn't quite capture the idea, just like understanding vectors only as n-tuples doesn't capture the real idea of a vector space (it's worth noting that tensors are also vectors: the tensor product of two vector spaces is itself a vector space).

  In a...

  Matrices and tensors are not the same thing. A tensor is not a matrix in exactly the same way that a vector is not an n-tuple. Coordinates are not the same thing as the objects they represent. This is why, for example, we can speak of vector spaces of functions. A matrix can be ...
