In this paper, the perturbation problem for a periodic logistic equation with indefinite weight functions and nonlocal dispersal is studied. The goal is to determine the asymptotic behavior of positive solutions for both large and small dispersal rates. It is shown that the positive solution uniformly approaches the maximum nonnegative solution of the kinetic equation as the dispersal rate tends to zero. However, when the dispersal rate tends to infinity, the positive solution converges uniformly to the maximum nonnegative solution of the kinetic equation, which is independent of spatial locations. The main results reveal that a large dispersal rate corresponds to a pure kinetic equation, while a small dispersal rate corresponds to a kinetic equation with parameters.
In this paper, we study the perturbation problem for the periodic logistic equation with indefinite weight functions and nonlocal dispersal. Our aim is to find the precisely asymptotic behavior of positive solutions when the perturbation (dispersal rate) is large or small. We establish that the positive solution uniformly tends to the maximum nonnegative solution of the kinetic equation as the dispersal rate goes to zero. However, the positive solution uniformly converges to the maximum nonnegative solution of kinetic equation, which is independent of spatial locations when the dispersal rate goes to infinity. The main results reveal that large dispersal rate corresponding to pure kinetic equation, whereas small dispersal rate corresponding to kinetic equation with parameters.
