central automorphism meaning in English

中心自同构

From these - two forms , we determine the automorphism group aut ( h ) of the ( 2n + 1 ) - dimensional heisenberg lie algebra h ( see theorem1 . 1 ) . moreover , some subgroups of aut ( h ) are obtained , such as the inner automorphism group , the central automorphism group , the involutional automorphism group , the first and the second extremal automorphism group
第一部分安排如下：首先给出了heisenberg李代数的两种定义形式，由这两种定义形式，我们得到了( 2n + 1 )维heisenberg李代数h的自同构群aut ( h ) (定理1 . 1 ) ；进而给出了aut ( h )的一些子群：内自同构群，中心自同构群，对合自同构群，第一类外自同构群，第二类外自同构群。
