A note on the tangent bundle of G/P
Let P be a parabolic subgroup of a complex simple linear algebraic group G. We prove that the tangent bundle T (G/P) is stable
A constructive method for decomposing real representations
A constructive method for decomposing finite dimensional representations of
semisimple real Lie algebras is developed. The method is illustrated by an
example. We also discuss an implementation of the algorithm in the language of
the computer algebra system {\sf GAP}4.Comment: Final version; to appear in "Journal of Symbolic Computation
Semisimple algebras of vector fields on C^N of maximal rank
A classification of semisimple algebras of vector fields on C^N that have a
Cartan subalgebra of dimension N is given. The proof uses basic representation
theory and the local canonical form of semisimple Lie algebras of vector
fields
