LetG= GLnbe the general linear group over an algebraically closed fieldk, letbe its Lie algebra and letUbe the subgroup ofGwhich consists of the upper uni-triangular matrices. Letbe the algebra of polynomial functions onand letbe the algebra of invariants under the conjugation action ofG. We consider the problem of giving finite homogeneous spanning sets for the-modules of highest weight vectors for the conjugation action on. We prove a general result in arbitrary characteristic which reduces the problem to giving spanning sets for the vector spaces of highest weight vectors for the action of GLr× GLson tuples ofr×smatrices. This requires the technique called “transmutation” by R. Brylinsky which is based on an instance of Howe duality. In characteristic zero, we give for all dominant weights χ ∈ ℤnfinite homogeneous spanning sets for the-modules $$ k{\left[\mathfrak{g}\right]}_{\upchi}^U $$ of highest weight vectors. This result was already stated by J. F. Donin, but he only gave proofs for his related results on skew representations for the symmetric group. We do the same for tuples ofn×n-matrices under the diagonal conjugation action.
