analytic automorphism operator

The author determines the real-analytic infinitesimal CR automorphisms of a class of pseudoconvex hypersurfaces in C~3 near the origin,and the unit connected component of the stability group of these hypersurfaces at the origin.

给出了C~3中一类拟凸超曲面定义在原点邻域内的实解析无穷小CR自同构,并得到了这类超曲面在原点处稳定群的单位连通分支。
