Derivations of the subalgebras intermediate the general linear Lie algebra and the diagonal subalgebra over commutative rings
Let be an arbitrary commutative ring with identity, the general linear Lie algebra over , the diagonal subalgebra of . In case 2 is a unit of , all subalgebras of containing are determined and their derivations are given. In case 2 is not a unit partial results are given.
