Description

Computes the tensor product of two Lie algebra modules.

i1 : g=simpleLieAlgebra("A",2)

o1 = g

o1 : simple LieAlgebra

i2 : U=irreducibleLieAlgebraModule({4,2},g)

o2 = U

o2 : irreducible LieAlgebraModule over g

i3 : V=irreducibleLieAlgebraModule({3,1},g)

o3 = V

o3 : irreducible LieAlgebraModule over g

i4 : U**V
