Hopf bifurcation analysis of Sel’kov model with time delay

open access: yesXi'an Gongcheng Daxue xuebao, 2023
The Sel’kov model with time-delay diffusion under homogeneous Neumann boundary conditions is considered. Firstly, the local asymptotically stability of the positive equilibrium point of the model is obtained by using spectral theory.

Dynamical Analysis of a Delayed Diffusive Predator–Prey Model with Additional Food Provided and Anti-Predator Behavior

open access: yesMathematics, 2022
We studied a delayed predator–prey model with diffusion and anti-predator behavior. Assume that additional food is provided for predator population. Then the stability of the positive equilibrium is considered.

Formulation of a computational asymptotic bifurcation theory applicable to hill-top branching and multiple bifurcation analyses

open access: yesNihon Kikai Gakkai ronbunshu, 2018
To diagnose hill-top branching and multiple bifurcation, which exhibit two critical eigenvalues of the tangent stiffness matrix in stability problems, a sophisticated computational asymptotic bifurcation theory is developed.
