Given a vector space V, there is a natural bilinear map V × V → F given by sending (v, φ) to the scalar φ(v). The universal property of the tensor product V ⊗ V automatically implies that this bilinear map is induced by a linear functional on V ⊗ V . Similarly, there is a natural bilinear map V × V → Hom(V, V) given by sending (v, φ) to the linear map w ↦ φ(w)v. The universal property of the tensor product, just as used previously, says that t… SpletAssuming that the symmetric matrix is nonsingular, summing the reciprocals of the eigenvalues nets you the trace of the inverse.
