WebThird-Order Tensors. The space of third-order tensors, T3, is most easily constructed by rst considering elementary tensor products of the form a b c for rst-order tensors (vectors in V) a;b;c 2T1. A third-order tensor can be used to de ne a linear transformation from Tp! T3 p for p= 0;1;2;3. The action of a third-order elementary tensor ... WebIn mathematics, the tensor product of two vector spaces V and W (over the same field) is a vector space to which is associated a bilinear map that maps a pair (,), , to an element of denoted .. An element of the form is called the tensor product of v and w.An element of is a tensor, and the tensor product of two vectors is sometimes called an elementary tensor …
