Can anyone tell me the GAP code to produce the derivations of a Lie algebra in matrix form?

I am a novice in using GAP. I can find the dimension of the derivation algebra but want to see the derivations displayed as matrices.

Is there an example of a solvable Lie algebra with non-characteristic nilradical?

It is well-known that the nilradical of a finite-dimensional Lie algebra over a field of characteristic p is not necessarily characteristic (that is, not invariant under all derivations of the...

Where does the algebraically closed field enter into Block's Theorem?

When applying Block's Theorem on the structure of differentiably simple rings to Lie algebras most authors require an algebraically closed field, but I can see no reference to algebraic closure in...

To what extent is context of fundamental importance in all investigations of axiomatic systems?

Some time ago a reviewer remarked "I am also wondering whether results about all kinds of Lie algebras are what we should be looking for. This is what you do at the earlier stages of a theory, may...

How can we include characteristic p in this work?

This is work in progress. If N is the nilradical of a solvable Lie algebra then its centraliser, C_L(N), is contained in N. The problem is to find a generalised version of the nilradical, N*,...

When M. I. Kuznetsov refers to a 1-graded Lie algebra in the below paper does he mean Z-graded?

M. I. Kuznetsov refers to a 1-graded Lie algebra in "Simple modular Lie algebras with a solvable maximal subalgebra, Math. USSR Sb30 (1976), 68–76". Does he mean Z-graded?
