Dynamics in diffusive Leslie–Gower prey–predator model with weak diffusion

open access: yesNonlinear Analysis, 2022
This paper is concerned with the diffusive Leslie–Gower prey–predator model with weak diffusion. Assuming that the diffusion rates of prey and predator are sufficiently small and the natural growth rate of prey is much greater than that of predators ...

Some examples for stable and historic behavior in replicator equations

open access: yesExamples and Counterexamples, 2022
The evolutionary dynamics of zero-sum and non zero-sum games under replicator equations could be drastically different from each other. In zero-sum games, heteroclinic cycles naturally occur whenever the species of the population supersede each other in ...

Low-Thrust Lyapunov to Lyapunov and Halo to Halo with $L^2$-Minimization [PDF]

open access: yes, 2016
In this work, we develop a new method to design energy minimum low-thrust missions (L2-minimization). In the Circular Restricted Three Body Problem, the knowledge of invariant manifolds helps us initialize an indirect method solving a transfer mission ...

Torsional vibration characteristics analysis and adaptive fixed‐time control of wind turbine drivetrain

open access: yesEnergy Science &Engineering, Volume 11, Issue 12, Page 4666-4686, December 2023., 2023
Aiming at the issue of torsional vibration characteristics analysis of wind turbine drivetrain, a mathematical model is established by considering electromechanical coupling effect. And a generalized Hamiltonian function can be used for Homoclinic or Heteroclinic bifurcation analysis.

Quasiperiodic, periodic, and slowing-down states of coupled heteroclinic cycles [PDF]

open access: yes, 2012
We investigate two coupled oscillators, each of which shows an attracting heteroclinic cycle in the absence of coupling. The two heteroclinic cycles are nonidentical. Weak coupling can lead to the elimination of the slowing-down state that asymptotically

A Three Dimensional Lagrangian Analysis of the Smoke Plume From the 2019/2020 Australian Wildfire Event

open access: yesJournal of Geophysical Research: Atmospheres, Volume 128, Issue 21, 16 November 2023., 2023
Abstract During the 2019/2020 Australian bushfire season, intense wildfires generated a rising plume with a record concentration of smoke in the lower stratosphere. Motivated by this event, we use the atmospheric wind reanalysis model ERA5 to characterize the three dimensional atmospheric transport in the general region of the plume following a ...

Scalar Field Evolution at Background and Perturbation Levels for a Broad Class of Potentials

open access: yesFortschritte der Physik, Volume 71, Issue 10-11, November 2023., 2023
Abstract In this paper, a non‐interacting scalar field cosmology with an arbitrary potential using the f‐deviser method that relies on the differentiability properties of the potential is investigated. Using this alternative mathematical approach, a unified dynamical system analysis at a scalar field's background and perturbation levels with arbitrary ...

Nonlinear stochastic dynamics research on a Lorenz system with white Gaussian noise based on a quasi‐potential approach

open access: yesInternational Journal of Mechanical System Dynamics, 2023
Environmental noise can lead to complex stochastic dynamical behaviors in nonlinear systems. In this paper, a Lorenz system with the parameter region with two stable fixed points and a chaotic saddle subject to white Gaussian noise is investigated as an ...
