A Light Intro To Tensors. A Framework For Defining Geometric

The tensor product of two vector spaces is a vector space that is defined up to an isomorphism. There are several equivalent ways to define it. Most consist of defining explicitly a vector space that is called a tensor product, and, generally, the equivalence proof results almost immediately from the basic properties of the vector spaces that are so defined. The tensor product can also be defined through a universal property; see § Universal property, be… Web28 Mar 2016 · First, the outer product is not linear as a map from V × V → Hom ( V, V). To see this, take any v, w ∈ V, pick any scalar λ ∈ R. Scaling the pair ( v, w) means scaling both components to ( λ v, λ w), and so the outer product is the matrix ( λ v) ( λ w T) = λ 2 v w T.
