【摘要】 以一类非可解矩阵李代数L为研究对象,利用分块矩阵的乘法运算,对L的导子及自同构进行了研究.借助于一种构造性证明的方法,证明了L的中心平凡且导子均为内导子,即L是完备李代数,并在R是特征不为2的整环的条件下,决定了L的所有自同构.更多还原

【Abstract】 Based on a non-solvable matrix Lie algebra L,the derivations and automorphisms of L were studied by the multiplication operation of block matrix.Using constructive proof methods,it is proved that the center of L is trivial and all its derivations are inner,in other words,L is shown to be a complete Lie algebra.Then,when R is an integer ring and its character is not 2,all the automorphisms of L are determined.更多还原
