Investigation of Bifurcations in the Process Equation

Abstract

This paper investigates the different behaviors of the process equation and parameters of their occurrences. The process equation is a multistable one dimensional map with nonlinear feedback and can show various behaviors such as period doubling route to chaos, bios, unstable windows and periodic windows. In this note, we focus on different behaviors of the process equation by a deep look at phase portraits and cobweb plots. Therefore, period doubling route to chaos and unifurcations of the equation are investigated, and also the parameter of its entrance to biotic pattern is discussed. The control parameter for the process equation is g (the coupling constant). In higher , the system shows some unstable and periodic windows among the biotic behaviors. Different patterns of these windows and the reasons of their happenings are investigated mathematically. In addition, some other types of unstable and periodic windows are discussed and Q-curves determine the difference of these windows with the previous ones.

Various bifurcations in the development of stem cells

“…The system’s different behaviors by parameter r were studied, such as equilibria, periodic, chaotic, and biotic dynamics. This model has been discussed in various studies [ 38 ]. Figure 1 shows the bifurcation diagram of Eq.…”

A novel chaotic map with a shifting parameter and stair-like bifurcation diagram: dynamical analysis and multistability

“…Chaotic maps can act as secret keys to convert plain image to an encrypted image in an image encryption process [15]. Modelling the dynamics of realworld and natural systems with the help of chaotic maps has also been a hot topic [16][17][18]. A discrete neuron model based on the Huber-Braun model was discussed in [19] to study the dynamics of a biological neuron.…”

Predicting Tipping Points in Chaotic Maps with Period‐Doubling Bifurcations

“…A piecewise linear system was studied in [14,15]. Discrete systems can show many exciting dynamics, while most dynamics can be investigated using an in-depth study of their structures [16]. e reliability of the dynamics of discrete systems is highly dependent on simulation time [17].…”
