摘要 考虑左定正则自伴Sturm-Liouville (S-L)问题,构造一个关于α的余切角,得到相应的分离边界条件,建立分离边界条件和耦合边界条件下左定S-L问题特征值间不等式. To study the left-definite regular self-adjoint Sturm-Liouville(S-L)problems,a cotangent angle ofαwas constructed and the corresponding separated boundary conditions were obtained.Thus,we established inequalities among eigenvalues of the left-definite S-L problems under separated boundary conditions and the coupled boundary conditions.
