Global stability and bifurcation analysis of a delayed predator-prey system with prey immigration
Electronic Journal of Qualitative Theory of Differential Equations, 2016 A delayed predator-prey system with a constant rate immigration is considered. Local and global stability of the equilibria are studied, a fixed point bifurcation appears near the boundary equilibrium and Hopf bifurcation occurs near the positive ...

Bifurcation at multiple eigenvalues and stability of bifurcating solutions
Journal of Functional Analysis, 1984 AbstractIf K is a bounded linear operator from the real Banach space U into the real Banach space V and ƒ:U×R→V has the value zero at (0, 0), the existence and linear stability of the equilibrium solutions of the dynamical system K dudt = ƒ(u, α) which are close to the origin in U×R are studied.

Stability and bifurcation on predator-prey systems with nonlocal prey competition
, 2017 In this paper, we investigate diffusive predator-prey systems with nonlocal intraspecific competition of prey for resources. We prove the existence and uniqueness of positive steady states when the conversion rate is large.

Experimental investigation of global stability against hunting oscillation using a real bogie
Nihon Kikai Gakkai ronbunshu, 2018 Hunting oscillation is unfavorable to the running stability because it can generate relatively large lateral force between the wheels and tracks. In addition, once hunting oscillation occurs, it lasts until the running speed is reduced to some degree ...
