摘要：
Let .2 and A be Lie triple systems, and let theta A be a representation of .2 on A. We first construct the third-order cohomology classes by derivations of A and .2, then obtain a Lie algebra G theta A with a representation 0 on H3(.2, A), where theta A is given by an abelian extension 0 // A //.2 tilde pi // .2 // 0 . We study obstruction classes for extensibility of derivations of A and .2 to those of .2 tilde . An application of 0 is discussed.
