Periodically Perturbed Hopf Bifurcation

SIAM Journal on Applied Mathematics, 1987
A general two-dimensional system of differential equations with periodic parametric excitation is considered with two real parameters one of them being the amplitude of the periodic excitation. As a matter of fact, the frequency of the excitation occurs also as an additional parameter, and in this respect the paper is related to the reviewer's results [

HOPF Bifurcation for Periodic Systems

1985
This paper concerns with the problem of Hopf bifurcation from an equilibrium position to periodic solutions, in the case of n dimensional periodic differential systems. Results about existence and uniqueness of bifurcating periodic solutions are obtained.

On Hopf and Subharmonic Bifurcations [PDF]

, 1984
Let (λ,x) ∈ ℝ×ℝn →f(λ,x) ∈ ℝn be a given function that, for simplicity, we shall assume to be of classe C∞. We also assume that the partial derivative Dxf(λ,x) is bounded, uniformly with respect to (λ,x) ∈ ℝ × ℝn.

Hopf bifurcation on a square superlattice

Nonlinearity, 2001
This paper concerns Hopf bifurcation equivariant under the group \(\Gamma:= D_4\ltimes T^2\), which acts \(\Gamma\)-simply on the phase space \(\mathbb{C}^8\). The problem is considered to be the centre manifold reduction of an evolution equation, invariant under the Euclidean group of planar translations, rotations and reflections, where the solutions

Equivalence of degenerate Hopf bifurcations

Nonlinearity, 1991
It is a very degenerate situation in Hopf bifurcation theory that all (bifurcating) periodic solutions occur for the parameter value of the bifurcation point. In principle such a singularity has infinite codimension. Therefore the problem of classification and equivalence of such bifurcation problems is very difficult.
