Journal of Differential Equations, 1979 INTRODUCTION Imperfection-sensivity theory for structures has been the subject of many studies for some fifteen years [3][11][16]. I n mathematical terms, this theory leads to problems of perturbed bifurcation. In this respect, the British School [16][17] has studied systems with a finite number of degrees of freedom.

On the torus bifurcation in averaging theory [PDF]
Journal of Differential Equations, 2020 In this paper, we take advantage of the averaging theory to investigate a torus bifurcation in two-parameter families of 2D nonautonomous differential equations. Our strategy consists in looking for generic conditions on the averaged functions that ensure the existence of a curve in the parameter space characterized by a Neimark-Sacker bifurcation in ...

Discrete prey-predator model with fear effect and strong Allee effect
Xi'an Gongcheng Daxue xuebao, 2023 The rich dynamic properties of a discrete prey-predator model with fear effect and strong Allee effect are studied. The piecewise constant argument method of differential equation is used to discretize the system, and the existence of equilibrium point ...

Abelian integrals and bifurcation theory
Journal of Differential Equations, 1985 Conditions are given for uniqueness of limit cycles for autonomous equations in the plane. The results are applicable to codimension two bifurcations near equilibrium points for vector fields.

Some New Results on Charged Compact Boson Stars
, 2017 In this work we present some new results obtained in a study of the phase diagram of charged compact boson stars in a theory involving a complex scalar field with a conical potential coupled to a U(1) gauge field and gravity.

The classification of bifurcations with hidden symmetries [PDF]
, 2000 We set up a singularity-theoretic framework for classifying one-parameter steady-state bifurcations with hidden symmetries. This framework also permits a non-trivial linearization at the bifurcation point.

Network topology drives population temporal variability in experimental habitat networks
Population Ecology, EarlyView.Habitat patches connected by dispersal pathways form habitat networks. We explored how network topology affects population outcomes in laboratory experiments using a model species (Daphnia carinata). Central habitat nodes in complex lattice networks exhibited lower temporal variability in population sizes, suggesting they support more stable ...

Analysis on recurrence behavior in oscillating networks of biologically relevant organic reactions
Mathematical Biosciences and Engineering, 2019 In this paper, we present a new method based on dynamical system theory to study certain type of slow-fast motions in dynamical systems, for which geometric singular perturbation theory may not be applicable.
