報告摘要:
In this talk, we shall discuss the effect of diffusion and frequency on the principal eigenvalue of linear time-periodic parabolic operators with zero Neumann boundary conditions. Monotonocity of the principal eigenvalue and its asymptotic behavior, as diffusion rate and frequency approach zero or infinity, are established. This leads to a classification of the topological structures of level sets for the principal eigenvalue, as a function of diffusion rate and frequency. This is a joint work with Professor Yuan Lou.
