Full cross-diffusion limit in the stationary Shigesada-Kawasaki-Teramoto model

Kousuke Kuto

This paper studies the asymptotic behavior of coexistence steady states of the Shigesada-Kawasaki-Teramoto model as both cross-diffusion coefficients tend to infinity at the same r…

High multiplicity and global structure of coexistence states in a predator-prey model with saturation

Kousuke Kuto, Julián López-Gómez, Eduardo Muñoz-Hernández

This paper establishes that, under the appropriate range of values of the parameters involved in the formulation of the model, a diffusive predator-prey system with saturation can…

On the unboundedness of the ratio of species and resources for the diffusive logistic equation

Jumpei Inoue, Kousuke Kuto

Concerning a class of diffusive logistic equations, Ni [1, Abstract] proposed an optimization problem to consider the supremum of the ratio of the L^1 norms of species and resource…

On the effects of protection zone and directed population flux in prey-predator dynamics

Kousuke Kuto, Kazuhiro Oeda

We study a spatial predator-prey model in which prey can enter a protection zone (refuge) inaccessible to predators, while predators exhibit directed movement toward prey-rich regi…

Large time behavior of solutions to a cooperative model with population flux by attractive transition

Ryuichi Kato, Kousuke Kuto

This paper is concerned with a diffusive Lotka-Volterra cooperative modelwith population flux by attractive transition. We study the time-global well-posedness and the large time b…

Bifurcation structure of steady-states for a cooperative model with population flux by attractive transition

Masahiro Adachi, Kousuke Kuto

This paper studies the steady-states to a diffusive Lotka-Volterra cooperative model with population flux by attractive transition. The first result gives many bifurcation points o…
