For example the state of a pendulum is its angle and angular velocity, and the evolution rule is Newton's equation Mathematically, a dynamical system is described by an initial value problem . The implication is that there is a notion of time and that a state at one time evolves to a state or possibly a collection of states at a later time. Thus states can be ordered by time, and time can be thought of as a single quantity. Dynamical systems are deterministic if there is a unique consequent to every state, or

Universality (dynamical systems) From Wikipedia, the free encyclopedia Jump to: navigation search This article needs additional citations for verification Please help improve this article by adding reliable references . Unsourced material may be challenged and removed (March 2010) 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. The term is slowly gaining a broader usage in several fields of mathematics, including combinatorics and probability theory , whenever the quantitative features of a structure (such as asymptotic behaviour) can be deduced from a few global parameters appearing in the definition, without requiring knowledge of the details of the system. The renormalization group explains universality. It classifies operators in a statistical field theory into relevant and irrelevant. Relevant operators are those perturbations to the free energy, the imaginary time Lagrangian, that will affect the continuum limit, and can be seen at long distances. Irrelevant operators are those that only change the short-distance details. The collection of scale-invariant statistical theories define the

Category:Dynamical systems From Scholarpedia This page is not peer reviewed. Contributors to this page are not anonymous. Only curators can edit it. A Dynamical system in mathematics is a system whose state in any moment of time is a function of its state in the previous moment of time and the input. Dynamical systems, in the form of ordinary differential equations of discrete mappings, describe most physical, chemical, and biological phenomena. Dynamical systems theory studies the solutions of such equations and mappings and their dependence on the initial conditions and the parameters.

Periodic -pseudo orbits form the R R is the chain recurrent set, R . This set is of fundamental importance in dynamical systems. Due to the theoretical and practical difficulties involved in the study of C , computers will presumably play a role in such efforts. Our aim is to use computers not only for inspiration, but to perform rigorous mathematical proofs. In this dissertation, we develop a computer program, called Hypatia , which locates R , sorts points into components according to their -dynamics, and investigates the property of hyperbolicity on R . The output is either "yes", in which case the computation

Computer Science Graduate Program Robots, Brains and Complex Dynamical Systems Home Introduction Target Audience Research Areas ... How to apply Blackbox modeling of complex dynamical systems Brains, stock markets, speech, dance, mobile robots driving on unknown grounds, video data streams and uncountable other dynamical systems can hardly be modelled analytically. But models are needed nonetheless to predict, filter, control, or just simulate such systems. In this situation, one can resort to blackbox models. Blackbox models are very flexible, general-purpose mathematical structures that can mimic the input-output dynamics of a large variety of target system. Standard examples are digital filters, neural networks, or hidden Markov models. Shaping a model such that it mimics a given empirical data set is variously known as learning (in Artificial Intelligence), system identification (in signal processing and control engineering), or model estimation (in statistics). Learning algorithms typically involve the estimation of hundreds to millions of parameters. Blackbox modeling research at IUB focuses on dynamical system modelling (as opposed to static pattern modeling) and on nonlinear and non-additive noise stochastic systems: Fast learning algorithms for recurrent neural networks (RNNs) Mathematical analysis of dynamics in RNNs

Wiki: Dynamical system This article is about the general aspects of dynamical systems. For technical details, see Dynamical system (definition) . For the study, see Dynamical systems theory "Dynamical" redirects here. For other uses, see Dynamics (disambiguation) A dynamical system is a concept in mathematics where a fixed rule describes the time dependence of a point in a geometrical space . Examples include the mathematical models that describe the swinging of a clock pendulum, the flow of water in a pipe, and the number of fish each spring in a lake. The Lorenz attractor is an example of a non-linear dynamical system. Studying this system helped give rise to Chaos theory At any given time a dynamical system has a state given by a set of real numbers (a vector ) which can be represented by a point in an appropriate state space (a geometrical manifold ). Small changes in the state of the system correspond to small changes in the numbers. The evolution rule of the dynamical system is a fixed rule that describes what future states follow from the current state. The rule is deterministic ; in other words, for a given time interval only one future state follows from the current state.
