Monodromy problem for the degenerate critical points
For the polynomial planar vector fields with a hyperbolic or nilpotent critical point at the origin, the monodromy problem has been solved, but for the strongly degenerate critical points this problem is still open. When the critical point is monodromic, the stability problem or the center- focus problem is an open problem too. In this paper we will consider the polynomial planar vector fields ...
متن کاملDynamical systems: recurrent and uniformly recurrent points
10.2. Example We consider the abstract dynamical system given in 9.18: the shift system over S where the phase space X is the product space {1, . . . , r}, for some r ≥ 2. For any R ⊆ S, there are x and U such that R(x, U) = R: simply pick x ∈ X be such that x(s) = 1 iff s ∈ R; so x might be considered as a characteristic function of R. Put U = {z ∈ X : z(1S) = 1}, a clopen subset of X. Then fo...
متن کاملCrashes as Critical Points
We study a rational expectation model of bubbles and crashes. The model has two components: (1) our key assumption is that a crash may be caused by local self-reinforcing imitation between noise traders. If the tendency for noise traders to imitate their nearest neighbors increases up to a certain point called the “critical” point, all noise traders may place the same order (sell) at the same t...
متن کاملCritical Points 3
We consider manifolds M which admit smooth maps into a connected sum of S × S with only finitely many critical points, for n ∈ {2, 4, 8}, and compute the minimal number of critical points.
متن کاملFractionalized Quantum Critical Points
Groundstates of certain materials can support exotic excitations with a charge that’s a fraction of the fundamental electron charge. The condensation of these fractionalized particles has been predicted to drive novel quantum phase transitions, which haven’t yet been observed in realistic systems. Through numerical and theoretical analysis of a physical model of interacting lattice bosons, we e...
