摘要: 该文证明了只有有限个非零元的无限矩阵构成的李代数的导子代数同构于每行每列都有限个非零元的无限矩阵构成的李代数模去其中心所成的商。同时证明这个商代数是完备李代数。Abstract: In this paper, it is proved that the derivation algebra of the Lie algebra of infinite matrices with finite nonzero entries is isomorphic to the quotient of the Lie algebra of infinite matrices with finite nonzero entries in each row and in each column nodulo its center. It os also proved that this quotient is a complete Lie algebra.
