Adjoint dimension of a direct Lie algebra sum/product [on hold]
Let $L_1,L_2$ be Lie algebras (not necessarily semisimple), $d_1,d_2$ the dimensions of the defining irrep and $D_1,D_2$ the dimension of the adjoint irrep. Let $L_3=L_1bigoplus L_2$ and $L_4=L_1bigotimes L_2$ and $d_3,d_4,D_3,D_4$ the respective dimensions of their defining and adjoint irrep. Can you express them in $d_1,d_2,D_1,D_2$? (Yes, the question is semisimple :-)

Would you mind adding a bit of context, describe the exact situation etc. ... As it is now, I for my part just don't understand the question.
