文摘Invariant symmetric bilinear forms and derivation algebras of a unitary Lie algebra L over R are characterized: (L) ≌ (R+/([R, R] A R+))* and Der(L) = Inn(L) + Der(L)0 = Inn(L) + SDer(R), which recover what of the special linear Lie algebra and Steinberg Lie algebra over R, where R is a unital involutory associative algebra over a field F.

文摘In this article, we discuss some properties of a supersymmetric invariant bilinear form on Lie supertriple systems. In particular, a supersymmetric invariant bilinear form on Lie supertriple systems can be extended to its standard imbedding Lie superalgebras. Furthermore, we generalize Garland's theory of universal central extensions for Lie supertriple systems following the classical one for Lie superalgebras. We solve the problems of lifting automorphisms and lifting derivations.
