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.
