摘要
讨论了一类具有耦合边界条件的左定四阶微分算子,利用具有耦合边界条件的左定四阶微分算子和其相应的右定四阶微分算子的关系,最终给出左定四阶微分算子特征值的计算方法.
In this paper, we study the left-definite regular self-adjoint differential operators with coupled boundary conditions. Using the relationship between the left-definite differen- tial operators with coupled boundary conditions and the right-definite differential operators of dimension four with coupled boundary conditions, we give an algorithm to compute eigen- values of the problems of left-definite four-order differential operators.
