Thus, if we have a Verma module W_\lambda with highest weight vector v, there will be a linear map \Phi from U(\mathfrak{g}) into W_\lambda given by.

Civil parishes in Worcestershire In mathematics, the tensor product of modules is a construction that allows arguments about bilinear maps (e.

multiplication) to be carried out in terms of linear maps.

To check that a tensor product M \otimes_R N is nonzero, one can construct an R-bilinear map f:M \times N \rightarrow G to an abelian group G such that f(m,n) \neq 0 .

\begin{cases} \operatorname{Hom}_R(M \otimes_R N, G) \simeq \{R\text{-bilinear maps } M \times N \to G \}, \\ g \mapsto g \circ \otimes \end{cases}.

Tensor product of linear maps and a change of base ring.

Given linear maps f: M \to M' of right modules over a ring R and g: N \to N' of left modules, there is a unique group homomorphism.

is that each trilinear map on.

corresponds to a unique linear map.

The tensor product of three modules defined by the universal property of trilinear maps is isomorphic to both of these iterated tensor products.

(tensor-hom relation) there is a canonical R-linear map:.

which is an isomorphism if either M or P is a finitely generated projective module (see for the non-commutative case); more generally, there is a canonical R-linear map:.

Like in the previous example, we have: \R \otimes_{\Z} \R \R \otimes_{\Q} \R as abelian group and thus as \Q-vector space (any \Z-linear map between \Q-vector spaces is \Q-linear).

Thus, E∗ is the set of all R-linear maps (also called linear forms), with operations.

An element as a (bi)linear map.

In the general case, each element of the tensor product of modules gives rise to a left R-linear map, to a right R-linear map, and to an R-bilinear form.
