摘 要: 对于给定的首项系数函数为正的Sturm-Liouville方程,利用在自伴边界条件空间上自然圈、边界条件的极限和特征值的单调性的几个结果,给出了在耦合边界条件与分离边界条件下的特征值间的一些等式的证明. For a given Sturm-Liouville equation with positive leading coefficient function,we use several monotonicity results about its natural loops,the limit of boundary conditions and eigenvalues on the space of self-adjoint boundary conditions.Using these results,we have given a proof of the equalities among eigenvalues for coupled boundary conditions and those for separated boundary conditions.
