Zhang, Hai Shan, A class of non-degenerate solvable Lie Algebras and their derivations, Acta mathematica Sinica. English series (Print) , 24(1), 2008, pp. 7-16
The author constructs a class of indecomposable non-degenerate solvable Lie Algebras g~ corresponding to a Cartan matrix A over the field of complex numbers and we determine all their derivations.
