Abstract:

摘要:We will discuss the asymptotic behaviors of principle eigenvalues for second order elliptic operstors with large drift. In the case of divergence free drift, we will propose certain functional associated with principal eigenfunctions of elliptic operator and its adjoint. The functional can be applied to establish the monotonicity of the principal eigenvalue, as a function of the drift amplitude. Other appications of such functional will also be discussed. The talk will be accessible to graduate students.
