摘要
利用算子直和分解的方法,研究了单项2n阶自伴向量微分算子谱的离散性,得到了这类微分算子的谱是离散的一个充分必要条件.
The discreteness of differential operator spectrum of2n-th order mono-term self-adjoint vector is studied with the method of decomposition of operator direct sum and a necessary and sufficient condition is obtained for that the spectra of this sort of operators should be discrete.
