摘要
主要讨论了由正则和奇异的2n阶对称微分算式生成的微分算子的积算子的自伴性,利用微分算子理论和矩阵计算,得到了I(I=[a,b]或[a,∞))上的积算子L=L2L1是自伴算子的充分必要条件.
The adjointness of the product of two differential operators generated by a 2nth-order symmetric differential expression is discussed. By means of the construction theory of differential operators and matrix computation,the necessary and sufficient conditions which make the product L =L2L1 being the adjoint operators in 1(1= [a ,b] or [a, ∞)) are obtained.
