WebbSeveral non-equivalent definitions of an attractor of a random dynamical system have been proposed in the literature. We consider a rather simple special case: random dynamical systems with state space [0, \infty) which fix 0. We examine conditions under which the set {0} is an attractor for three different notions of an attractor. Webb17 nov. 1992 · We study the existence of the random uniform attractor within the set of tempered closed bounded random sets for a family of first order stochastic non-autonomous lattice dynamical systems (LDSs ...
Webb24 sep. 2024 · Example: We put the names of every student in a class into a hat and randomly draw out names to get a sample of students. Benefit: Simple random samples are usually representative of the population we’re interested in since every member has an equal chance of being included in the sample. Stratified random sample WebbThe random attractor extends the concept of a strange attractor from deterministic to stochastic system. There has been great interest in random attractors for stochastic partial differential equations in recent decades. The random attractors are compact invariant random sets attracting all the orbits of attraction basin.
WebbUsing the lottery method is one of the oldest ways and is a mechanical example of random sampling. In this method, the researcher gives each member of the population a number. Researchers draw numbers from … Webb1 apr. 1997 · Finally, under a restrictive assumption on the monotonicity coefficient, we find that the random attractor consists of a single point, and therefore the system possesses …
WebbThe Lorenz attractor was the first strange attractor, but there are many systems of equations that give rise to chaotic dynamics. Examples of other strange attractors include the Rössler and Hénon attractors. The Rössler attractor arose from studying oscillations in chemical reactions.
