A Diagrammatic Representation of Phase Portraits and Bifurcation Diagrams of Two-Dimensional Dynamical Systems [PDF]
Javier Roulet and Gabriel B. Mindlin, Int. J. Bifurcation Chaos
27, 1730045 (2017), 2018 We treat the problem of characterizing in a systematic way the qualitative features of two-dimensional dynamical systems. To that end, we construct a representation of the topological features of phase portraits by means of diagrams that discard their quantitative information.

Some new results on charged compact boson stars
Physics Letters B, 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.

Bifurcation and Patterns Analysis for a Spatiotemporal Discrete Gierer-Meinhardt System
Mathematics, 2022 The Gierer-Meinhardt system is one of the prototypical pattern formation models. The bifurcation and pattern dynamics of a spatiotemporal discrete Gierer-Meinhardt system are investigated via the couple map lattice model (CML) method in this paper.

Bifurcation diagrams of the buck converter
9th International Conference on Electronics, Circuits and Systems, 2003 The steady-state responses of the buck converter are determined by means of computer simulation and presented in a form of one-parameter bifurcation diagrams and two-parameter bifurcation diagrams. It is shown that analysed converter can be driven into chaos through a process of period doublings for each of the three chosen bifurcation parameters: the ...

Deformations of the Bifurcation Diagram Due to Discretization [PDF]
Mathematics of Computation, 1985 With a singular perturbation problem occurring in chemical reaction processes, substantial changes of the bifurcation diagram due to discretization are demonstrated. It is shown that a discrete system can possess any number of solutions, whereas the underlying continuous problem has exactly one solution.

Dynamic study of a predator-prey model with Allee effect and Holling type-I functional response
Advances in Difference Equations, 2019 In this paper, a prey-predator model with Allee effect and Holling type-I functional response is established, and its dynamical behaviors are studied in detail. The existence, boundedness and stability of the model are qualitatively discussed.
