Abstract
Aslaksen, H., Determining summands in tensor products of Lie algebra representations, Journal of
Pure and Applied Algebra 93 (1994) 135-146.
We give some results that enable us to find certain summands in tensor products of Lie algebra
representations. We concentrate on the splitting of tensor squares into their symmetric and
antisymmetric parts. Our results are valid for any Lie algebra of arbitrary rank, but we do not
attempt to give the complete decomposition.
1. Introduction
The problem of decomposing tensor products of finite-dimensional representations
