On principal eigenvalues of linear time-periodic parabolic systems:
symmetric mutation case
The paper is concerned with the effect of the spatio-temporal heterogeneity on the principal eigenvalue of some linear time-periodic parabolic system. Various asymptotic behaviors of the principal eigenvalue and its monotonicity, as a function of the diffusion rate and frequency, are first derived. In particular, some singular behaviors of the …
