 \begin{example}\index{\(\mathfrak{g}\)-module!tensor product}
   Given a Lie algebra \(\mathfrak{g}\) and \(\mathfrak{g}\)-modules \(M\) and
-  \(N\), the space \(M \otimes N = M \otimes_K N\) -- the tensor product over
-  \(K\) -- is a \(\mathfrak{g}\)-module where \(X \cdot (m \otimes n) = X \cdot
-  m \otimes n + m \otimes X \cdot n\). The exterior and symmetric products \(M
-  \wedge N\) and \(M \odot N\) are both quotients of \(M \otimes N\) by
-  \(\mathfrak{g}\)-submodules. In particular, the exterior and symmetric powers
-  \(\wedge^r M\) and \(\operatorname{Sym}^r M\) are \(\mathfrak{g}\)-modules.

-  We should point out that the monoidal structure of
