离散哈密顿系统在极限圆型下的自伴扩张的等价刻画

摘要

运用线性关系理论,利用离散哈密顿系统的解,导出了一类一端奇异离散线性哈密顿系统在极限圆型时其最小子空间的任一自伴子空间扩张的等价刻画.%The equivalent characterization of any self-adjoint subspace extension of a class of singular discrete linear Hamiltonian systems with one end in the limit circle was given by means of the theory of linear relation and the solution of discrete Hamiltonian system.
