Complexity theory and nonlinear dynamic systems

  • What is non linear dynamic system theory?

    Nonlinear dynamical systems theory allows us to shift the perspective to the dynamic interactions and transitions among continuous yet qualitatively different types of reasoning.
    One consequence of this approach is that reasoning capacities are no longer understood as falling within two distinct kinds..

  • What is the theory of nonlinear dynamics?

    Nonlinear dynamical systems may be formally deterministic , in that if the initial conditions are known precisely then the state of a system can be predicted; however, the dynamical trajectories are highly sensitive to the initial conditions, so that small uncertainties can grow exponentially, a response popularly .

  • Why is nonlinear dynamics important?

    Nonlinear dynamics models can be used to study spatially extended systems such as acoustic waves, electrical transmission problems, plasma waves, and so forth.
    These problems have been modeled by using a linear chain of discrete oscillators with nearest neighbor coupling as shown in Figure 19..

  • Dynamic complexity asks for the effort needed to maintain the information about properties of a structure under operations changing the structure.
    This paper introduces a refined notion of dynamic problems which takes the initial structure into account.

  • Nonlinearity quite commonly arises through the collective behavior of even the simplest systems: it is insufficient to simply (linearly) add the effects of the components.
    Instead, the interactions between the components lead to such emergent phenomena as chaos, solitons, fractals and meta/multi-stability.
The study of complex systems and non linear dynamics is essentially an interdisciplinary field of research, involving mathematics, physics, chemistry, biology,.

System of ordinary differential equations with chaotic solutions

The Lorenz system is a system of ordinary differential equations first studied by mathematician and meteorologist Edward Lorenz.
It is notable for having chaotic solutions for certain parameter values and initial conditions.
In particular, the Lorenz attractor is a set of chaotic solutions of the Lorenz system.
In popular media the butterfly effect stems from the real-world implications of the Lorenz attractor, namely that several different initial chaotic conditions evolve in phase space in a way that never repeats, so all chaos is unpredictable.
This underscores that chaotic systems can be completely deterministic and yet still be inherently unpredictable over long periods of time.
Because chaos continually increases in systems, we cannot predict the future of systems well.
E.g., even the small flap of a butterfly’s wings could set the world on a vastly different trajectory, such as by causing a hurricane.
The shape of the Lorenz attractor itself, when plotted in phase space, may also be seen to resemble a butterfly.
In statistical mechanics, universality is the observation that there are properties for a large class of systems that are independent of the dynamical details of the system.
Systems display universality in a scaling limit, when a large number of interacting parts come together.
The modern meaning of the term was introduced by Leo Kadanoff in the 1960s, but a simpler version of the concept was already implicit in the van der Waals equation and in the earlier Landau theory of phase transitions, which did not incorporate scaling correctly.
