A center manifold at a given nonhyperbolic equilibrium is an invariant manifold of a given differential equation that is tangent at the equilibrium point to the (generalized) eigenspace of the neutrally stable eigenvalues. Since the local dynamic behavior transverse to the center manifold is relatively simple, the potentially complicated asymptotic ...

Isochronicity of centers at a center manifold
AIP Conference Proceedings, 2012For a three dimensional system with a center manifold filled with closed trajectories (corresponding to periodic solutions of the system) we give criteria on the coefficients of the system to distinguish between the cases of isochronous and non-isochronous oscillations. Bifurcations of critical periods of the system are studied as well.

Hopf bifurcation and the centers on center manifold for a class of three‐dimensional Circuit system
Mathematical methods in the applied sciences, 2019In this paper, Hopf bifurcation and center problem for a generic three‐dimensional Chua's circuit system are studied. Applying the formal series method of computing singular point quantities to investigate the two cases of the generic circuit system, we ...

Regularity Theory for 2-Dimensional Almost Minimal Currents II: Branched Center Manifold
, 2015We construct a branched center manifold in a neighborhood of a singular point of a 2-dimensional integral current which is almost minimizing in a suitable sense.

Center stable manifold for planar fractional damped equations
Applied Mathematics and Computation, 2017In this paper, we discuss the existence of a center stable manifold for planar fractional damped equations. By constructing a suitable LyapunovPerron operator via giving asymptotic behavior of MittagLeffler function, we obtain an interesting center ...

Construction of Center Manifolds
ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 1990AbstractGiven a pair of coupled differential equations ẋ = g(x, y), ẏ = h(x, y), x, y being vectors. The paper is concerned with existence and properties of invariant manifolds given in the form y = S(x), × ∈ M. The questions raised and partially answered differ from the standard content of center manifold theory in two respects.

In this paper, we use a feedback to change the orientation and the shape of the center manifold of a system with uncontrollable linearization. This change directly affect the reduced dynamics on the center manifold, and hence change the stability properties of the original system.

In this chapter we analyse the behaviour of the nonlinear semiflow near a nonhyperbolic equilibrium; that is, we consider the situation where A does have spectrum on the imaginary axis. We use the decomposition of X as $$X\, = {X_ - } \oplus {X_0} \oplus {X_{ + \cdot }}$$

Let \(X\) be a Banach space. Consider the semiflow \(\Phi:X\to X\) with \(\Phi(x) =U(x)+ g(x)\), \(U\in L(X,X)\), \(g\in C^k(X,X)\), \(k\geq 1\), \(g(0)=0\).
