Ning, Jin, Automorphisms of Infinite Dimensional Lie Algebras of Cartan Type, Acta Mathematica Sinica, New Series Chinese Journal of Mathematics, 13(2), 1997, pp. 155-160
Abstract In this paper it is proved that any automorphism of an infinite dimensional Lie algebra of Cartan type over an algebraically closed field of characteristic p> 2 can be induced from an automorphism of the associated divided power algebra.
