*Hausdorff Dimension of Attractors of Unimodal maps *
*If one wants to investigate properties of a dynamical system, one of
the first things to do is to check attractors of this dynamical system
and their properties. We will discuss Hausdorff dimension of attractors
of unimodal maps (i.e. maps of an interval with one critical point) and
show the following remarkable fact: Hausdorff dimension of an attractor
of a unimodal map with a non-degenerate critical point is either 1 and
in this case this attractor is a union of intervals or it is less than
some universal constant. This constant is strictly less than 1 and
does not depend on anything.*
