Strange attractors may also be found in the presence of noise, where they may be shown to support invariant random probability measures of Sinai–Ruelle–Bowen type. Visa mer In the mathematical field of dynamical systems, an attractor is a set of states toward which a system tends to evolve, for a wide variety of starting conditions of the system. System values that get close enough to the … Visa mer Let $${\displaystyle t}$$ represent time and let $${\displaystyle f(t,\cdot )}$$ be a function which specifies the dynamics of the system. That is, if $${\displaystyle a}$$ is a point in an Visa mer Attractors are portions or subsets of the phase space of a dynamical system. Until the 1960s, attractors were thought of as being simple geometric subsets of the phase space, like points, lines, surfaces, and simple regions of three-dimensional space. … Visa mer Parabolic partial differential equations may have finite-dimensional attractors.

WebbIn mathematics, the attractor of a random dynamical system may be loosely thought of as a set to which the system evolves after a long enough time.
