Predictable, or tame, attractors correspond to the behavior to which a system settles down or is "attracted". A strange attractor is represented by an unpredictable trajectory where a minute difference in starting positions of two initially adjacent points leads to totally uncorrelated positions later in time or in the mathematical iteration. 3, record 1, English, - attractor

Recursion relations are also used to construct fractal attractors characteristic of chaotic motion. As a simple example we briefly mention dynamic systems that period double on their way to chaos... However the set invariant with regard to(2. 19) is a repeller(not an attractor). It can be shown that the attractor forms approximately a non-uniform Cantor set. 4, record 1, English, - attractor
