题目：On Asymptotic Behaviors of Principal Eigenvalues for Second Order Elliptic Operators

主讲人：刘爽

邀请人：张晓燕 数学学院教授

摘要：The study on the qualitative properties of principal eigenvalue for second order elliptic operators has a long history. In recent years there are some interest in investigating the monotonicity and asymptotic behaviors of such principal eigenvalue with small diffusion or large advection rates. In this talk we will discuss some recent works along this line, and try to find some global information on the principal eigenvalue, i.e. the classification of topological structures of the level sets as a function of multiple parameters. This enables us to better understand qualitative properties of the principal eigenvalues.
