Web15 Oct 2010 · The inner product (also called the metric tensor) defines a natural isomorphism between V and V*. If we let g act first on only one vector of V, we get the dual vector g (u,_). In more conventional notation, your dyadic product of two vectors of V can be written. EDIT: There's a close-bracket missing in the last equation.
