An application of global Weyl modules of $\lie{sl}_{n+1}[t]$ to   invariant theory
  We identify $\lie{sl}_{n+1}$--isotypical components of global Weyl modules with natural subspaces in a polynomial ring, and then apply the representation theory of current algebras to classical problems in invariant theory.
