Collision and Annihilation of Relative Equilibrium Points Around Asteroids with a Changing Parameter [PDF]
, 2015 In this work, we investigate the bifurcations of relative equilibria in the gravitational potential of asteroids. A theorem concerning a conserved quantity, which is about the eigenvalues and number of relative equilibria, is presented and proved. The conserved quantity can restrict the number of non-degenerate equilibria in the gravitational potential

Fractal basins in an ecological model [PDF]
Computational Ecology and Software, 2013 Complex dynamics is detected in an ecological model of host-parasitoid interaction. It illustrates fractalization of basins with self-similarity and chaotic attractors. This paper describes these dynamic behaviors, bifurcations, and chaos.

The Effect of Susceptible Immigrants in a System Dynamic on the Spread of Malaria in Indonesia
JTAM (Jurnal Teori dan Aplikasi Matematika), 2022 The spread of malaria is a serious public health problem, including in Indonesia. The mathematical model is formulated to describe the dynamic nature of the spread of malaria. The model used in this article is the SIR-SI model. This article discusses the

Analysis of degenerate Chenciner bifurcation [PDF]
International Journal of Bifurcation and Chaos Vol. 30, No. 16,
2050245 (2020)Degenerate Chenciner bifurcation in generic discrete-time dynamical systems is studied in this work. While the non-degenerate Chenciner bifurcation can be described by 2 bifurcation diagrams, the degeneracy we studied in this work gives rise to 32 different bifurcation diagrams.

Simplified Chua's attractor via bridging a diode pair
The Journal of Engineering, 2015 In this paper, a simplified Chua's circuit is realised by bridging a diode pair between a passive LC (inductance and capacitance in parallel connection - LC) oscillator and an active RC (resistance and capacitance in parallel connection - RC) filter. The

Ultradiscrete Bifurcations for One Dimensional Dynamical Systems [PDF]
, 2020 Bifurcations of one dimensional dynamical systems are discussed based on some ultradiscrete equations. The ultradiscrete equations are derived from normal forms of one-dimensional nonlinear differential equations, each of which has saddle-node, transcritical, or supercritical pitchfork bifurcations.
