Bogdanov–Takens Bifurcation of a Class of Delayed Reaction–Diffusion System
International Journal of Bifurcation and Chaos, 2015In this paper, a class of reaction–diffusion system with Neumann boundary condition is considered. By analyzing the generalized eigenvector associated with zero eigenvalue, an equivalent condition for the determination of Bogdonov–Takens (B–T) singularity is obtained.

DETECTING BOGDANOV–TAKENS BIFURCATION OF TRAVELING WAVES IN REACTION–DIFFUSION SYSTEMS
International Journal of Bifurcation and Chaos, 2006In this paper we investigate the onset of instabilities in a model describing the propagation of the steady planar premixed combustion wave. In particular, we are interested in determining the Bogdanov–Takens bifurcation condition, which is investigated semi-analytically.

Invariant circles in the Bogdanov-Takens bifurcation for diffeomorphisms
Ergodic Theory and Dynamical Systems, 1996AbstractWe study a generic, real analytic unfolding of a planar diffeomorphism having a fixed point with unipotent linear part. In the analogue for vector fields an open parameter domain is known to exist, with a unique limit cycle. This domain is bounded by curves corresponding to a Hopf bifurcation and to a homoclinic connection.

Hopf and Bogdanov–Takens Bifurcations of a Delayed Bazykin Model
Qualitative Theory of Dynamical SystemsIn this paper, the authors investigated the Hopf and Bogdanov-Takens bifurcations of a delayed Bazykin predator-prey model with predator intraspecific interactions and ratio-dependent functional response. And they established sufficient conditions for the existence of Hopf bifurcation.

In this paper, a neutral Hopfield neural network with bidirectional connection is considered. In the first step, by choosing the connection weights as parameters bifurcation, the critical point at which a zero root of multiplicity two occurs in the characteristic equation associated with the linearized system.

In the parameter space, curves of (classical) Poincare–Andronov–Hopf bifurcations, saddle-node bifurcations and homoclinic orbits emerge.In this chapter, we discuss the intricate patterns of heteroclinic orbits which appear near the corresponding bifurcation without parameters.

Study of a degenerate bogdanov-takens bifurcation in a family of mechanical oscillators
Mechanics Research Communications, 1998The authors study nonlinear second-order ordinary differential equations as models of generalized oscillators, and detect periodic behaviour by analysing the bifurcations in these oscillators. The most degenerate equilibria are considered, and a useful information is given about nontrivial oscillatory behaviours and their transitions. In particular, it
