报告摘要:This report is one of a series of reports on the spectral theory of Sturm-Liouville operators. In the first talk,the properties of the first eigenvalues for Sturm-Liouville problems is considered. The accurate asymptotic formula of the first eigenvalue on the ``jump set” is given. The results indicate that the asymptotic behaviors are only related to the values of the coefficients of the equation in the neighborhood of the end points.

报告摘要:This report is one of a series of reports on the spectral theory of Sturm-Liouville operators. In the second talk,the application in biology mathematics of the first eigenvalues for Sturm-Liouville problems is discussed in detail. We discuss the monotonicity of the first eigenvalue with respect to parameters involved in both equations and boundary conditions. The infimum of the parameter which guarantee the monotonicity of the first eigenvalue is obtained.
