摘要: 研究了具有内部奇异点,即直和空间上的高阶对称微分算子辛几何刻画问题。由于对称微分算子在
端点处的亏指数取值情况不同,当微分算子在端点处均取(n,n)时,通过构造商空间,应用辛几何的方法讨论了直
和空间的对称微分算子的自共轭扩张问题。给出了与二阶对称微分算子自共轭域相对应的完全Lagrangian子流型
的分类与描述。

Abstract:  

Interior singular points were mainly studied in this paper,which means the characterization of self-adjoint domains for symmetric differential operators in the direct sum spaces. There exist the different deficiency indices at (n,n)singular points.Therefore by constructing different quotient spaces and using the method of symplectic geometry, it is possible to study self-adjoint extensions of symmetric differential operators in the direct sum spaces.The classification and description of complete Lagrangian submanifold that corresponds with self-adjoint domains of second order differential operators were also produced .

Key words: Differential operators, Symplectic spaces ,  , Lagrangian submanifold  ,  ,  Singular points,  , Direct sum spaces
