报告题目: On an eigenvalue problem and its application
发布单位:金宝搏亚洲体育        浏览次数:17        发布时间:2022年04月25日

报告摘要:A linear eigenvalue problem governed by a second order differential equation with separate and general boundary conditions is considered and a new monotonicity result on the principal eigenvalue with respect to the coefficient of the advection term is established. The main approach is based on the functional proposed by Liu and Lou and a key finding lies in the nice properties of the associated Frechet operator when confined at suitable points and function spaces. As an application, this monotonicity result is used to study a class of competitive parabolic systems and the so-called exclusion principle is observed in a larger parameter region than several existing works, which is a nontrivial improvement.
