The Strong Disjoint Blow-Up/Collapse Property by Héctor N. Salas

“…We introduce the Strong Disjoint Blow-up/Collapse property and prove that if satisfy this new property, then they have a dense linear manifold of disjoint hypercyclic vectors. This allows us to give a partial affirmative answer to one of their questions.…”

The Hopf Bifurcation for a Predator-Prey System with -Logistic Growth and Prey Refuge by Shaoli Wang, Zhihao Ge

“…Time delay could be considered as a bifurcation parameter for DDEs, and using the normal form theory and the center manifold reduction, explicit formulae are derived to determine the direction of bifurcations and the stability and other properties of bifurcating periodic solutions. …”

Dynamics of a Computer Virus Propagation Model with Delays and Graded Infection Rate by Zizhen Zhang, Limin Song

“…In succession, direction and stability of the Hopf bifurcation when the two delays are not equal are determined by using normal form theory and center manifold theorem. Finally, some numerical simulations are also carried out to justify the obtained theoretical results.…”

Bifurcation analysis of HIV-1 infection model with cell-to-cell transmission and immune response delay by Jinhu Xu, Yicang Zhou

“…Moreover, the direction of the Hopf bifurcation and the stability of the periodic solutions are investigated by normal form and center manifold theory.Numerical simulations are done to explore the rich dynamics,including stability switches, Hopf bifurcations, and chaotic oscillations.…”
